I had mine on a dyno and it read 452 rwhp. If you factor in a 17% parasitic loss, that is about 544 crank hp which was just shy of where it was supposed to be.

The problem they had with my car was the tires. They were older tires and due to the light weight of the car and IRS, were slipping on the dyno. I think the dyno was a Mustang with 24" rollers. I have not put it back on since the good tires were installed.
