I don't know how someone doesn't see boost before 1600 rpm, something is wrong with that truck. My gauge would fluctuate around 1lb at idle, and would get to 3 or 4 by 1100 and 10 by about 1400-1500. Once it hit 15-18 it would take off like a rocket. I'm anxious to get it on my current truck and see how it does.

 

I love them I got'm from john link in MI. he's a cool guy and super reasonable. pm me if you want his number
