I mean I did order it all together but yes I can tell and hear it better. But what helps the hsp alot is the tuning also

Just asking bc I ordered a high flow kit for my lbz like y bridge and everything and was hoping I was gonna benefit from it. Especially since I tow a 40ft camper

@chasekiser2965 it should. Only pros really. It will help let your truck breathe better and give it more power but like I said tuning is where it will compliment it

I have efi live on my truck. I have to get it retuned bc I just did 30% over injectors and a 65mm turbo

then you should be golden!
