Greddy kit will about pretty good power. I dyno'd my car with the turbo and FMIC at 4 psi untune at 129 whp 130 wtq. thats at 4 psi though. my engine stock (d16y8) prolly puts down 95 whp and no wtq
. so thats about 10 hp per psi which is avg but my A/F ratio was really really rich so I lost some power. but its still impressive for just a turbo.
