boost help

i just did the boost mod with the red line.. i took her for a test drive had in 80 horse power economy from dp tunes. I noticed it is raising the boost level quicker but still only got 20 psi... I read its suppose to get near 30 with the mod. Is it just i didnt have enough fuel to reach the higher boost numbers or whats my problem?


any suggestions

your waste gate may be poping open. The spring in it probably isnt strong enough to keep it shut. try wiring it shut and take it for a drive, if it gets higher then thats your problem.
