ok i just got my car back from the tuner shop, but there is a few problems and i was wondering if anyone can help. the internal wastegate is set to 7 psi, but right now its only pushing 2 psi. what should i check or does anyone KNOW what might be wrong or need changed. the tuner told me to take it home cause i had to have it that day, and to check out all my Vac. lines and recheck everything. i got a garret t25 internally wastegated, with a bosch bypass valve, 2001 mustang gt MAF and IAT, autometer boost gauge(must be hooked up right its reading 2 psi) well if anyone can help give me a shout.
