i just chipped my 2001 tip s4 with giac
a week later i felt a huge power loss it felt normal in first but in 2nd and on it felt like there was no boost at all. im thinking its obviously a boost leak probably tbb but i dont hear the wooshing sound that everyone hears when their tbb is cracked. is this a boost leak for sure or could it be something else?

Pressure check- most like a leak but it could also be Throttle cut.

and have the weak points checked out... I've torn the TBB, blown both DVs, popped an IC hose, had my EGT sensors go bad, exhaust leak from the turbo, had my K03s overspun etc. etc..... all led to power loss and/or uneven boost.
