Won't go over 10-12PSI after ZZP stage 3
I'm wondering if some experienced folks on here can help me out.
I just finished the ZZP Stage 3 installation including a dual-pass endplate and surge tank. I bought the stage 3 kit with the 2.8" pulley and 60# injectors.
The car gets to 10-12psi faster, but won't hit the 17-18 expected from the 2.8" pulley. I would have imagined the ZZP canned tune would have set the diverter/bleed valve to open after the expected boost level of 17-18--if this is what's even preventing the boost.
I sent an email to Tim over at ZZP and am waiting on his comments. I did a bit of research on the bypass mod, but I feel I shouldn't have to muck around with it because of the new PCM tune.
