So is that effectively the difference between bhp and whp? It sounds like it (about 10-15%), since the dynojet usually dyno higher than the Mustang ones.

If that is the case, then that would make me sad, since our cars are supposed to come stock with 230bhp. This was also the AA 1st gen tune too, right?
