Went back to check the area the pull was made, the difference in slope was after the 1/8th mile section we were testing in but I kept driving it out so the numbers on the 1/8 mile were on the same slope of less than 1 degree difference.

The Draggy is crazy accurate compared directly to track ET/MPH! Our testing showed +- .02-.05 accuracy! 👍👍👍

I’ve been using dragy for a year now. The results differ by 0.1 with track times at most. It depends on how I stage the car. I use custom mode to measure the acceleration on 3rd gear pulls and use it as a road dyno

Been using G-Tech's for years. Very accurate if no wheel spin and was within a couple .01"s at the strip. Great for tune dialing.

definitely a great and helpful alternative when you want to tune and cant find a loaded dyno, or track thats open

For those wanting to set up custom speeds to start and stop your tests, click "connect" on your Dragy app and then press "+" That will take you to a page with "defaults" on the upper left side and "custom" on the right. Select custom. Click "add" and enter your speed range. This helps with dialing in ignition timing at full throttle because you start at the same speed and can tailor it to allow a full pull in one gear (shifting will introduce error and won't allow for a consistent comparison with each timing change).

Hey man really appreciate the content! Your channel content rivals some paid content I’ve received. Also, I bought a dragy after watching this video. Much easier to see if improvements are real, next best thing to a dyno. Would be cool if HP tuners could accept data from dragy

Im glad you proved your point on vvt.. what settings should be applied to achieve the same results.. EDIT. Nvm.. you have a video already... you rock man!

I been looking at grabbing one of these for awhile now. Just kinda waiting for the winter to let up. Finally buying hptuners. Step dad has a 6.2 ford he wants me to turbo (and efilive won’t tune them obviously). I’m terrified because late model ford tuning is alien 👽 We need a ford goat rope lol Love the truck btw. I have it’s older brother.. black 2007 nnbs rcsb. 4.8 with cam/Fbo/nitrous. Just my “daily” but She’ll beat a hellcat to the 1/8!

Dragy yes! What a tool! Perfect, exactly what I need. Thanks!

When your local track opens up. Compare the draggy to the track.

What about the Track Addict app?

The whole idea in tuning is to make it better! Right? Yes the factory cares more about emissions than mpg or hp. Did you pull in the same direction? I also noticed you didn't show your cam tune. That would have been most helpful!

I'm assuming you have used HP Tuners' Track Addict before... How the the numbers stack up against each other? Is one more accurate than another? Track Addict is free so is it really worth the $120?

i got a draggy box last week and cant get it to read right, hooked it up to two separate cars that are proven low 2 second 60's and it was showing 6+ seconds. First car the trans brake kept triggering the timer so that's something to think about if you looking at this

I would say 3 run average using the same place on the road in the same direction to eliminate headwind effect with both tunes

Draggy seems to be awesome but the VVT you just proved what you’ve been preaching brother.

New to your channel just found it today planning on learning how to tune I've had HP tuners for a while now and dont know how to use it tuning wise I can do some basic stuff but wanting to learn how to t Tune good stuff I have 84 Chevy c10 with 99 exslade frame under it with a 05 2500 6.0 4l80 awd transfer case

what is the name of the application to test car on drag?

How does this compare to the Hp tuner track addict ?

2.93% vs -0.29% slope. Over 3% difference on slope has an effect on your acceleration times.

I just ordered one after watching this.

Sometimes i think he has a few drinks before some of these videos. Nothing wrong with that though.

We didn't get to see the cam tables?

Vvt is beneficial to power gains. I can confirm. On a caliber srt4. I made 430 whp on the stock cam timing setup. I then went in and advanced the intake and exhaust cams. No overlap as turboed cars do not need or want any overlap. Then smoothed it out after 3500 rpm and retarded the cams by 5 degrees by redline. And gained 30 whp to make 460 to the tire. We retard them up top to get the air out quicker. And advance down low to help with spool

I have a few different vehicles in the “garage” part of the dragy app. Do you know how to associate a run with a vehicle, so when it saves you know what vehicle the times are for?

I personally believe the vvt can make more power, but I 100 percent believe the stock tuning of it is only for emissions

You should have done like 3 runs for each or something like that

I hadn't mine hard wired in so it's always charging.

Sick DA you got cookin' there.....

If only HPTuners would spend a little more time on their track addict app... I may have to look into the draggy.

VVT makes today's performance possible. Without it they would not pass EPA standards and wouldn't make production. So in a way, you can say It has plusses in performance as well as emissions.

Your second run was pulling uphill vs down on the other

The only flaw i see is that at 9:15 when you're attempting another run, you just had sat in the truck idling, for a couple of minutes prior. So i'm assuming the engine has been a bit heatsoaked. You should have driven up that road, then u-turn back, then right back to that starting point so the air would have cooled down the engine a bit. IMO that's why the 0-60 was a little slow, because the computer probably pulled timing.

Why can’t they implement a simple 20-100mph? Some people want to test new mods without relying on ideal launch 🤦‍♂️

Cool. Unfortunate that you have a gear change right around 57mph otherwise you'd be a lot quicker to 60mph

Is it really any better than HP tuners Track Addict?

I see u have the Welsh flag in the background what's the story to that??? + great vid

What video software do you use to do split screen? Pretty nice!

I’ve seen tuners gaining 50 hp on stroked engines by turning off vvt completely

dragy not draggy
