27psi on S256?
So I bought a Cobalt running on 91 because I'm from Québec, Canada and the car's pushing 511hp. Turbo is pushing 27 psi ish. Is this too much for the S256? Can it hold more? I just don't want to buy another turbo because I ran it with too much boost...
FBO, external wastegate + dump tube, BOV, Catless DP, Rear and front trans mount, Engine mount.

was runnin 32-34psi on mine for 2 years never had an issue, pump e85 w/100shot of a nitrous on top of that.
pump 91 is rough though, need to add some octane if you're going to push much more
