This is who people need to see for B58 quality content. Well done sir!

Thank you so much for this information... I've been searching like crazy for this info about stock Tü and aftermarket hpfp.. thank you again for sharing this video with us.

Dunno if it's worth mentioning, but these are just off the shelf GM LT1 (stage1) and LT4 (stage2) pumps. Lingenfelter makes a big bore (+~10% flow over the LT4) version of this pump that should be straight drop-in for either of these kits once you move the lash cap over and rotate the connector. Basically any upgrade made for the GM LTx motors should be direct fit here with Dorch's adapter plate, lash cap, and plumbing, which is pretty cool.

Running almost a year on dorch stg2 Great products for bigger turbo

You just helped me answer my question on buying an HPFP. My B58TU handles more than I thought given I will keep the stock turbo. My stage 2 with a catted downpipe, updated air intake, amd MHD should be ok. Now I have to think about the intercooler...

Thank you for the quality content you provide!

Thank you for the making of this video I needed some guidance when it came to this

Amazing vid, learnt loads, thank you for these in depth vids man!

Thanks again for another in depth, straight to the facts video my good friend ❤️ eagerly waiting for the next one

Man you are everywhere… I was in the forums yesterday and you popped up, then less than a day later I’m poking around on KZfaq and you’re the first video that pops up… you’re the BMW guru that’s crazy. While I have you here; I want to upgrade a turbo on a m240i, I’m mainly just looking for like stock+, nothing crazy, I’m not trying to wear down my cars components nor am I trying to upgrade every single little part, I feel like you start running into issues doing that. I just want to set it and forget it. Once I’m done I’m done, I don’t want to tinker, I want to have it installed, get it tuned and that be it. I’d like to be around 550hp on 93. I’m okay with adding a fuel pump, a down pipe, and a tune. What is the best option for me? Which is the least fuss and most reliable/OEM feeling of the bunch? Pure 800/850? I would go top mount if that was the best route, money isn’t really the limiting factor, it’s more so I want to remain more stock than not stock. If you say top mount with DP and fuel pump best suits my needs, that’s okay. If you could recommend the FP and DP and tune to go along with it that would be great as well. Thanks Guru!

Well spoken with great details 🔥🔥🚀🚀🚀

Excellent video. Very informative. Thanks for producing it!

Awesome information.. Very well done. You helped me with my decision for sure.. Thanks a bunch

you think stage 1 dorch will be fine with a hybrid turbo like Pure Stage 2 and some E30? Goal is to just be 500-550Whp!

Thank you so much for this video. I watched it a while back but am still learning. I came back today and watched it again and know everything you are talking about. I have a 540 and I'll buy the TU pump. I'm not upgrading my turbo and am fine w/ no more than 550hp, but will go w/ a tune, High flow down pipe, high flow intake and this TU pump.... we'll see what that gives me. I'll also buy new Coil packs and new plugs. If anyone here has some recommendations/lessons learned... I'd really - really, appreciate your input.

Stage 2.5 now.

Awesome vid, thanks!

Great video

I really like your videos very informative

Hey kern, this video is old but just want to know I have the dorch stage 1 hpfp and want to go flowmax tubo 2.5v+ . Would the dorch stage 1 support a e50 blend or do I need to upgrade? Or which blend would be best with the upgraded turbo

According to several websites, the TU pump should support up to 575 - 600 HP on the crank. I'm currently running stage 2+ with the TU pump, and planning to go for a hybrid turbo at around 550 hp crank (RON 98 fuel only). The TU pump should be sufficient for this power goal? The given max power numbers for TU seem a bit optimistic.

Hi, I want to get hybrid turbo and get 600crank on 99 ron fuel. I have supra, so allready tu pump but is it enough for this power? What about single turbo and power like 700 crank on pump fuel 99 ron? I don’t want to run E blend as I don’t have where to store it in Europe and we don’t have ethanol at the peteol station. Thanks a lot

I want the dorch stage 2 hpfp but cant afford it for 2 grand because UK salaries are shite 😢

@kern417 if running stock turbo b58 with stg2+ tune from MG flasher E40 map is there any power benefit from running dorch2 instead of TU pump? Dorch2 makes more flow so power will be bigger with dorch2 or will be the same as with tu pump on E40 stg2+ map ?

Hey man what turbo and hpfp you recommend for a 2018 x3 m40i. I have bootmod3, downpipe and chargepipe. Got crappy gas out here. 91oct pretty much all there is

Has anyone had a rattle from the b58 tu fuel pump, mine is very noisy ticking

Just a heads up. I emailed Dorch about just swapping the HPFP alone and keeping the stage 1 lines and rail (when changing to a stage 2 HPFP) they said I should change all the lines and rails.

How much power will the stage 1 support? Do you think it can support 675whp or even closer to 700whp on a e40-5-0 mix?

My tu pump works well in my n55

Tu pump is roughly $400 and dorch stage 1 is $1200. Is the extra money worth the lower bar pressure?

Just to clarify, u couldn’t use the dorch ones on a stock tune??

I just had dorch 2 installed with the base map from mhd to run while I wait for my custom tune. That should be okay with no issues right ?

Wait dorch doesn’t work on the TU engines? Just stuck with the TU pump?

Thanks for another informative video, I had a question that maybe you'll have some insight on. I only have 92Oct local to me so I run MHD STG2 on the 91 tune but was curious to run the 93 tune, is it close enough to run no problem? would throwing octane booster in every tank make it safe? Or is the tune so potentially similar it doesn't matter? Thanks ahead if you have any insight!

Thanks and we’ll done on great content. Any word at all on a hpfp for the TU engines? I saw your video explains why it’s unlikely but asking anyway.

All I have to do is get the tu to run e30 or is there other upgrades needed

If you’ve installed your DE stg2 already, did you get your nut that couples the rail and pump together to thread all the way on? Other two go all the way down by hand when I installed how the manual says but the one that goes to the pump won’t go all the way down. Is that normal or should I keep messing with the alignment?

One question, Can I go full e85 or e85 mix with premium and upgrade my hpfp to Dorch stg 1? I have stock turbo and cts intake with mhd tune on my b58.

Can I use the stock fuel pump with my BM3 stage 2 tune? Everything is stock on my G30 except the downpipe.

Besides price, is there any reason to go with dorch stage 1 vs stage 2? Like fuel economy? I plan on eventually going bigger turbo but not for a while, would I benefit from sticking with stage 1 for now until going bigger turbo and then go with stage 2?

Ever since I changed out to the TU fuel pump, I can not get my tune to give me the extreme burbles. I even flashed it and set the aggression to 12 at 1.5, 1.7, 2.0, and 2.5.... I can't get the cracking and pops like I used to ( Stage 2 - 93 Oc.) Bootmos3..... HELP Please

what problems did you run into to decide a fuel pump?

@kern417 Out of curiosity since i dont really know how to flows work i know you put it in the video but to dumb it down for me lol, what mix is achievable with the TU? surely it isnt full e right or is it?

@kern417 so I installed the TU pump, and ran into the issue of the fuel lines not lining up seamlessly with the rail and pump etc. I too had to man handle the rails into place. I’m kind of concerned about leakage though, the flared ends are off to the side, and I tightened tf out of them. Was leaking a concern for you? I drove it, got on it a little and brought it back to the garage. I don’t see any leaking. But I’m curious as to how it’s going to handle on an e40 map with higher pressure. Thoughts?

Hey Kern, I'm sorry if this is a dumb question. If we were to run a TU pump on our cars would we need a custom tune to run 91 octane, or could we simply use the Stage 2 91 OTS bm3 tune? There isn't a selection for the TU pump in the tune config, only Dorch and Spool. I'm asking because where I'm at ethanol is hard to come by, but I'm moving somewhere where it is more common. I figure I'd install it and run it on 91 and then switch to an E30 tune, but there is no OTS Stage 2+ 91 octane tune. Thanks!!!

Can I us e a b58 first gen hpfp on a 2013 bmw 135i n55 engine?

if you are on stock turbo, could you skip hpfp upgrade and get port injection? just a random idea i had. not sure if it would work. any thoughts or feedback? Thank you!

Hi @kern417 massive fan here from the UK. I need to ask. I'm currently running BM3 stage 2+ on my gen 1 b58 M240i with the TU HPFP and loving it. However I would like to flash back to stock for the winter months my question is can I keep the TU HPFP on the car and just select OEM in the map configuration settings so the car thinks the standard pumps on, or would I need to install the stock pump? Cheers, appreciate your continued help. J

Truly the best B58 content in the world. Thank you so much brother 🫶🏾 Excited to take the next step from my is350 to a 340i

? I have a 1st gen and I have a jb4, I’m adding a high flow down pipe… therefore I should be good with e30 without upgrading to a tu fuel pump; correct? The whp shouldn’t go above 450ish I’m guessing Thx sir

I have a 2019 540xi which pump does my car come with does the b58 tu come with the TU pump or no?

You can turn the connector of the TU pump into the right way..

Hallou, is TU Fuel pump sufficient for Stage 2+ MHD?

So i have gen 1 its a 2019 540xi but its gen 1 pump so if i upgrade to dorch stage 2 do i need to upgrade anything else like injectors? Amd what turbo should i upgrade to? Im stage 2 MHD ots and catless plus intake and charge pipe

Looking to do a TU pump with PI meth on a pure 800. How much do you think ill make? I think ill go with a E30 blend

would I benefit at all from running a TU pump if I am only intake+jb4 (map3)? I get the occasional lean fuel code

Does your car have upgraded suspension? My car has been feeling weird lately but i have no idea what it is its riding rough even in comfort mode and i can hear every little bump in the road.. kinda annoying

Good video brother!! I have a cold air intake and high flow catted downpipe on the way for my gen 1 b58 (18’ 540i). Once I install the CAI and DP I want to go stage 1. Do you think I’ll be good w the TU/Supra hpfp?? Thank man!!

Based on your b58 tuning guide video, ive decided to go stick with a stage 2+\2.5 on my 2018 440i. If im looking to tune with MHD and run a VRSF catless downpipe, would i even need the dorch stage 1? Or could i get away with the TU?

What’s the max E blend I can run with the flex fuel kit from BM3 on the stock Gen 1 pump?

Can you use the TU pump without ethanol ? Just on stock turbo stage 2 93 octane?

Is it risky for the cam to run aftermarket pumps on a gen 1 b58? I have a downpipe and tune and i just want to prevent any catastrophic failures. I also like to run a bm3 standard 91 octane tune to make about 400 whp

thoughts on going with a dorche stage 2 on a stock gen1 b58 engine/turbo?

I do not plan on going big turbo I’m just wanna run the stage 2+ tune from bootmod3 should I by the tu bump or the dorch stage 1 I have Hurd story’s in forums of the tu pump eating the cam or blowing a injector have you hurd if any of theses issues and what would you recommend

Can i run TU pump on Stage 2 91(ACN) ? Or would i need to go to Stage 2+ ?

Later we can expect Dorch Stage 2 fuel pump for B58 second generation (Supra)? thanks!

What’s the max WHP you figure someone can get on an m340i B58tu Catless downpipe JB4 Tune with EWG connecter

Have people had any problems with TU pump on the gen 1 b58

Why doesnt the dorsche stage 2 make more whp compared to tu pump?

Hey Kern ik this videos old but I was looking into getting the mhd flex fuel kit but since I live in cali we’re limited to 91, would I see any gains by getting the tu pump over stock if i’m only gonna be running 91 most of the time with e30 used on weekends?

Do you think I could run full e85 with the tu pump on Mhd stage 2 hpfp ?

Yo boss , I got a tu pump . I’m planning to make atleast high 500s / 600 whp . Would I be able to achieve that ?

hi kern quick question i have 2017 540i planning to run bootmod3 stage 2 93oct do you think it would make sense to invest in the tu pump ?

Do you plan on keeping your old pumps, or are they already gone?

Will Dorch Stg1 be enough for Hybrid Turbo with e30/meth?

Do you know much about jb4? I got a 18 340i running map 4 on 93oct. Gonna switch to mhd flasher soon

What is the highest ethanol rating the Supra tu pump can run in only looking to run e50 on my “fastest map” will it hold and do okay ?

Anyone run this on F10 535i PWG?

If staying stock turbo, would you go TU pump or Stage 1? Planning on stage 2 tune and maybe e-30 mix once a Gas ⛽️ station comes near by.

Hi guys can I use the HPFP TU for my first gen b58 m140i? I'm running only MHD / XHP stage 1 and was looking for a cheap upgrade.

How you feel about Fuel It HPFP??

Does the hpfp affect gas mileage?

is it safe to run pure850 with dorch stage 2 on stage 2+e30?

I'm running mhd stage 2 e30 map and the car is happy. Logs show rail pressure sitting at or below 3k psi and I'm running about 18psi boost under load. Should I upgrade the fuel pump or is this happy?

anybody has information about the Dorch or Fuel IT stage 2 pump, what brand or source these are? Because I do not believe, these are made by the tuners it self... I am sure only the install hardware is custom. I would be very thankful for this information..🤗 Thanks in advance!

Could I run a dorsch hpfp on a 2021 supra? On the dorsch website it says that their pumps are not compatible with 2020+ supras b58. Why is that so?

Beyond sound and stage 2 upgrades.. the rest for the price just buy a car with more power lmao.

if i have mhd stage 2, catless b58, 93 pump gas, should i get a tu? i might get an upgraded turbo in the future. what kind of difference would it make with/without an upgraded turbo?

a question, can i run a bm3 stage 2+ E50 with a dorch stage 1? I have original turbo

On stock turbo, what’s the max I would need for stage 2+ tune on 91 octane? Catless+intake. I’m thinking TU would be plenty to max out the stock turbo?
