Hey guys so I just installed a stage 2 Hahn kit recently and a Aeromotive 1309 fpr instead of the crappy one that comes with the kit. Is it ok to run boost with just that (93 octane/8.5 compression btw)?
 
On something with such extensive modification that was never meant to run on forced induction I wouldn't recommend anything more than 4 psi without the ability to monitor wideband A/F and personally I wouldn't run any boost without the ability to monitor it as well as make adjustments to fuel timing etc.
 
I do have a boost guage and its set at 8 psi but no wideband.

Get a wideband. Want to know your AF ratio? Welp, that's the only way you'll know, and will be the safest way to know whether or not you're about to blow up your motor.
 
Have you done anything for fuel and tuning? 16g turbos run the stock 450 injectors on the turbo DSMs pretty hard at just 10 PSI.
 
Ok I do have the Hahn Portfueler at the house but wasnt gonna put that in till next week ill drive real easy till then.
