68mm Turbo Boost, What am I missing
So recently I installed a Dans Diesel 68mm turbo on my truck. I have an add-on EAS pressure sensor to my CTS2 to measure my boost in my cold side pipe. I also have PPEI efi and trans tunes. When I sent them several data logs to tune the new turbo, the PID they use to show boost is around 38 psi but my sensor on my CTS is showing about 28-30 psi max. The system has been pressure tested and has no leaks. What am I missing here? I read all over the forums guys running much higher boost than me and I want to make sure this new turbo is being fully utilized, but having 10 psi of boost missing has me concerned.
