I realize this, and I have presented the reasons why. AA's Mustang dyno just reads lower than the majority of dynos out there. They still don't read the lowest as in the DynoDB there is a stock car making only 305 hp on a Mustand dyno. That car must really be broken by the logic in this thread. The reason for this thread and the FACT is that they got me another 20 hp and my car runs great.
