Just got the tuner and installed it.. today when I give the truck hell (full throttle) the psi goes up to 34psi on the psi guage on the trintiy. Seems like way to much. What boost should I be getting with the 91 octane tune? I'm new to tuning and new to the turbo world... don't want to blow up.the motor. Am I reading it wrong? Do I need to cut it in half because it's twin turbo? Feel like an idiot but I gotta ask...

sounds like it is displaying MAP + BARO, so subtract 14.7 from that for correct boost, which would be 20 psi, which is about where it should be.
