Not sure to be honest. I've never had it dyno'd. I was holding out until I could get either an SAFC or a full stand alone to tune & dyno it. These are rated at 200hp from the factory, and with all the mods I've got, I'm guessing I'm getting 225-250 to the wheels. That is a guess from what I know about the car and other cars that have dyno'd with similar mods. I'm only running about 12psi right now and it is still pretty fast to me.
