03 with HORRIBLE turbo lag
 

Hey Guys.

Have an 03

New injectors
SB intake
4inch turbo back
and thats it



LAtely i have had some serious turbo lag. I am holding up traffic when i have my enclosed trailer behind me.


Have been to 2 different dealers. One my friend works at. And both the diesel tech says something is up but they cant find out what it is.


I get ZERO boost until 2300rpms. and dont get above 15psi until 2nd gear.

No smoke, no codes, new DRY air filter.

I just got back form a ride aling witht the tech 2 hooked up and rail pressure is good. boost reads the same on the tech 2 as it does on my gauges.


IM at a loss. I thought is was my MAF so we put a brand new GM one in and that didnt change a thing.


HELP!!
