New to forum truck runs good since I bought it 4 months ago haven't noticed any difference but I just installed the cts monitor to use for gages and barely showing and boost here is my readings
Boost idle 0psi- cruising 1psi- on the throttle 9psi
Map psi idle 13 psi on the throttle 16psi
Back pressure 2psi idle on the throttle 17psi
Egts idle around 200 cruising 70mph around 700 when on the throttle
around 1100
You think I got a bad sensor not showing right boost or leak in boost system?

 

Truck has intake ,ts chip, stock exhaust without muffler

 

What throws me off is the 9psi on the throttle for your boost gauge but only a gain of 3 psi on your MAP.

 

Before going any further, we need some basics. Key on, but engine off - what is the MAP, EBP, and BARO reading?
