Well, i have my dealer searching for a crew cab 2500 4x4 Duramax. I need some advice on mods cuz FIRST Thing I am going to get a programmer, exhaust, CAI and Wheels/Tires. SO what do you suggest?? IVE heard Good about the PPE programmer, but what about the Edge/juice/Attitude. Where can i get a reasonably price 5'' Exhaust with cat delete pipe and no muffler? What do you guys like for cold air intakes? I want to do it once and do it right. Thanks for the replys-Tim

 

Forget all of those first and get yourself a Boost guage and EGT Guage. That is your most important first mod. Then I'd get a programmer and Exhaust. If your dealer is finding a LBZ duramax the stock intake is just as good as any CAI out there so don't even worry about that.

 

They are looking for a left over 06 but im might just buy an 07 if i cant find one, Im getting impatient!! I know how important the gauges are coming from a turbo gas engine. What is the scale for EGT's ? what is stock boost set at and what is the safe limit for a stock LBZ?

 

That was the case for me. I wanted an 06' but they could never located the one I wanted. I didnt want bose or leather etc which is all that was left so I just bought a 07 Classic.

i think the stock turbo puts out about 20-23 psi on stock program

 

Ok, so boost is adjusted up or down via Tuning?

 

i think it varies some but most turbo applications use the wastegate to control boost ( which you more than likely already know from the sts) but i think the duramax turbo has an internal wastegate

 

yeah, i wandered if the D-max had a computer controlled wastegate.

 

i believe it is but it is inside the turbo housing and the turbine vanes have varying angles controlled by the computer

 

Tim the best thing for you to do is like RubenZ and I have said... join and READ. It is the best thing you can do. You will learn more and save $$$$
