This is a solid kit from what we have seen. 420whp on a mustang dyno on 9PSI. Made about 330ft/lbs of torque. Had a nice powerband really. I applaud them for taking a kit back just because the customer wasn't happy with dyno numbers. You could have just told him to go run on a dynojet! haha.
Thanks,
