Factory boost numbers
Have a boost question, and for some reason, the site is not currently letting me search the forum for an answer. So if this is redundant, I apologize.
I have a 2002 ccsb, zf-6, 4x4, banks intake, mbrp 4"exhaust, factory injectors and turbo, canned ts-6, 235,000 miles. According to my torque app, I never produce over 14.9 psi boost, even WOT at the +100hp setting. I'm guessing that I either have a leak somewhere, or since this thing was bone stock when I bought it, there is an adjustment somewhere that I know nothing of, which will jump my numbers. Is the factory wastegate limited to 15 psi, and can I adjust it? I have seen other members with similar upgrades claim to get over 20 psi.
Any and all help is appreciated, but please understand that I cannot afford any more upgrades at this time and have to rely solely on tuning what I have at this point. I'm not upset with the performance I am getting, just want to peak what I have.
