what should the boost level reach when i am right to the mat. im already having electrical problems with a wiring harness but now i am feeling like i am getting turbo lag

 

Max boost depends on how loaded the truck is and how hot it is. Definately above 30 psi unloaded and can approach 40 psi under the right load and heat buildup.

 

Unloaded, I have reached 34psi. under hard acceleration.

 

I have hit 40psi on hill with load and 30psi without load.

 

With DPF delete, and tuner I have seen 52psi towing 10K up a good grade....empty while under WOT I can see 42-46 all the time.

Before I did the tune and DPF delete I never seen 40, and hardly ever 30psi...but then again, I only had it stock for like 700 miles.
