V8 bogging

[slidewayzz]

Alright, so before it was bogging, so i did a few donuts, because last time it fixed itself and it worked. Amidst doing donuts, my fuel pump went out. Towed home.

I fixed all my wiring/ fuses.. I also fixed my gas tank, which had a cut/leak. I replaced my walbro 255 fuel pump, with same exact one.

It primed, fired right up! Manual FPR, running 4bar like it should.
Exhaust has a leak, and one header has a crack, but before it ran fine, but bogged when i bought it and randomely went away.

Swap: Ls2, 6.0l/t56

Idles perfect, BOGS WHEN YOU STEP ON IT!

Need immediate answers! Thanks alot!

Check for vac leaks and check wiring

just out of curiosity is your car blue?

[slidewayzz]

It is not blue.

I'll check for vacuum leaks with carb cleaner tomorrow morning. Any other suggestions before that time? Car is not located on my property so i would like to know a bunch of things to check while i'm at it. Thanks.

Can you get a obd scanner? That will help pinpoint problems. I had similar problems with mine and it turned out that I wired my knock sensors wrong. Same setup

sounds like you have a fuel presure problem. maybe a Fuel presure regulator?
