What degree should i set the intake and exhaust cams for the hahn stage 2 setup? Im wanting to run about 13-18 psi and i have already built the motor from top to bottom.

DYNO tune the settings are different for every car.
a dyno is the only way to know, sure you can use what others have usedor go by the seat of your pants but when youve spent good money on turbo kits/cams,etc.. dont skimp on the tuning.

dyno with wideband o2 sensor is around 125 bucks for 3 pulls, which is enough to tune your car correctly.
