Plan on running low boost no higher than 3-7 psi anytime soon. Im guessing the stocker cant keep up but since my truck is an 06 i have heard through the grapevine that it is a weird year for the pump setup. Do i need a fuel pump for this low of boost?


Anything on the 2006 that anyone knows about? Want to order me a pump pretty quickly so any help is appreciated. Unless the stock pump will suffice for low boost.

Thanks!!

 

i would never run a stock fuel pump being boosted, get a walbro 255.

 

Yes i thoughts so...... just need someone with some experience on the install on a 06

 

Bump for some info !

 

2006 gmc sieera 5.3, TVS 1900 running 9lbs of boost on stock pump. Never had an issue, Justin as blackbear said its golden. Its also my daily i pound the **** outta too

 

Dang man!!
Do you have a wideband guage?
Your probably the first person I've seen say the stock pump is fine lol
That's not a bad thing though!
Ever look at your AF ratio under full throttle ?

 

Also what injectors are you running ?

Thanks

 

Anyone ?

 

The flexfuel pump is a little bigger than the stock one, but I would still upgrade to a walbro400 or 450.

 

I just replaced my 255 for a 450. If I were you I would just skip the 255 for the 400 or 450 like Atomic said. Its only a few more dollars and pushed enough fuel for my single.
