dumbest shit ever
we had an STS kit on our GTO at UTI, the car put down mid 3's bone stock, put the sts kit on and got 370ish out of it.
figured ok somethings not right, smoked both the intake and exhaust sides, found a couple leaks. threw it on the load cell made sure the tune was spot on.
up'd the boost to 15, still only put down 415
biggest waste of money ever, and dumbest looking shit ever. we could have got farther with a big cam and a 50 shot
