ok so i recently blew my s14 T24 BB turbo. my SR20 was ROM tuned on the dyno for 480cc, T28, 14 psi, n60 maf. now heres the question, i just put on an HX35(holset) and i REALLY need this car for daily driving. can i get away with driving the car with the holset just pushing about 7.5 psi? cause thats what my Tial wastegate has on there now. thanks.

Better yet, slap it on and dont fucking let it boost just to make sure. 7.5 psi on a big ass turbo aint gonna be the same air flow as 15 psi T28.

ahaha for sure mang. i'm thinking it should be fine as long as i don't boost higher than like 5psi

yep you should be ok! But... if driving your car is anything like mine? The boost demon is always on your back. My cure was a silencer 1" opening. made the car sound like sh*t! And lowered boost from 1bar to .77bar. Gave me enough time to realize what i was about too do!
