hi everyone. i just brought a 93 jdm supra [auto] and it use to run 11-12 psi when it was stock. today i got a 3" exhaust from turbo back and now its running 16 psi. ive done nothing else to it apart fom a k&n air filter. is this normall or is something wrong.i thought boost cut comes in bout 14-15 psi. thanks for the help.[ive got no boost controler or anything like that]

i just went for a drive and it boosted to 18 psi, is it safe to continye to drive a that much boost?

becareful , of your af's, you can blow the turbos or even ruin the motor, doing long pulls on 18psi, timing is pulled alot without 100octane...

a few short pulls with 93-94pump 18psi is fine, but not long periods of time...

keep it @15psi if you want ur turbos to live, 18-20psi is fine with higher octane remember

qik supra, do u have a boost controller and/or BBC or a reprogrammed ECU?
