This is a customers truck, I found this truck to be way to lean and down on power. I will disable the extra injector garbage and install large injectors with a custom tune. Headers and exhaust will follow to get a good start. Also a boost leak may be an issue as well, it did sound funny at the time of dyno.

Sorry for the thread jack but I cant start my own...... I don't usually see the wipples but one came today. Only 4psi max and a lean A/F, I have some work to do but is 4PSI the norm? Whipple won't tell me shot. Oh stock exhaust with a flowmaster (not helping out) Thanks TODD.

I don't think that 6.2 will blow my fish out of the water. Of course I will need a couple of months build time.

note taken.

Well thanks Mr.P for the info..... The rest, thanks for the off topic thread jack. TODD

I have seen the new GM truck body style on the lots, when will the 6.0l trucks hit market. I was told the first production run was of 5.3l. TODD
