So i bought the ZZP S/C kit and love it! i went down to sea level and was making 9psi with the stage 1! well i came back home and i am only making 3 psi of boost and my car feels like a boat now xD what can i do to get my 9 psi back? i have 2.5" exhaust all the way with no cats or res or 2nd 02 sensor.

do i upgrade pulleys?
is my MAP sensor not working?
grr so confusing and i want my power back haha it was 3 grand ugh

 

What altitude do you live at? With a stock pulley at 2800ft I was making 6-7 psi near 5700 rpm.
