The only problem I'm having is too much boost pressure, the n75 lets the excess out but it kindof bounces around at the 18psi mark. I ordered a mbc to run like johnnybravo says to smooth it out. I will keep you updated.

y are you running so much boost?

Hes got a k03 chip

so is the gpop k04 an actual k04 or is it just a k03 with upgraded bearings and blades. cuase its deff. alot cheaper then the k04's from other places.
