My gf just got 03 ss silverado with a whipple on it runs like crap. She wants to remove it Bring truck back to stock. My questions are what parts will I need to buy to remove it?? Also I want to install on my truck which is a 4.8 instead of 6.0 what will I need??? One more. How much psi should it have during boost. Idle it's reading 25 psi an 40 ish wide open, don't really go good at all my 4.8 seems have more power thanks a lot

 

I would do a compression test on the 6.0 and the boost gauge is not reading right at all. Shouldn't be any boost at idle.

 

Are you talking about oil pressure..?

 

Remove the whipple carp tronics, add real injectors and a tune.
And save for a tranny upgrade.

 

I have a bran new tranny in the ss so that's coverd At idle there isn't any boost but when u step on gas gauge goes up like 15 lbs which I'm sure isn't right. An the fuel psi during full boost is only sayn about 40 tops according to the gauge. When it runs like crap the yellow mil light comes on. I'm very new to the forced induction world. No matter what the supercharger coming off the ss an goin on my truck. U say get rid the whip ple computer Crap ok so how do I go about this what will I need. Your talkin about the silver box that says whipple I can remove this when I add this kit to my truck ?? Thanks for any help

 

It don't have boost during idle. Sorry not clear with what I was saying it has 25 psi on fuel gauge at idle an 40 when flooring it. I think I read it supposed be 59 psi wide open during boost ?

 

Anyone I'm wanna take the whipple of the ss in next cpl days what parts will I need. An will it bolt right on the 4.8??

 

What year is the 4.8 truck?

 

It's a 99 4.8

 

Swap everything from the 6.0 to the 4.8.
Get some good injectors and a tune.. that takes care of the crappy electronics.
