VAST Boosting question... need advice from the pros!
When I hold 4th gear, I'm seeing 25-27 PSI. I cant really look for too long because im hauling ***, but should that be turned down a notch? I don't want to overboost my turbos. Little backround on my setup, is im @ sea level first off, second im running their latest stuff RS4 Airbox Hitachi RS4 MAF, Bosch GG Injectors, straight piggies, no cats at all blah blah.

Ohok, I didnt think you could read up that high with stock MAP sensor...
its also the new style AWE gauge so ive tested it before its accurate

Well slightly lower, I guess I can ask, do they tune boost only in 3rd? ....
its not like the turbo wont blow because the boost in third is OK and fourth is higher LOL.

MBC and turn it down a bit, my setup was overboosting like that before as well
except even in 2nd and 3rd, it was scary fast but i could tell it wasn't going to be good for the long haul. VAST MBC in parallel and clip those spikes.
