The only accurate dyno for an auto is with a locked converter. And I'm willing to bet a considerable amount the OP didn't have his locked.
Who cares how the torque is made? It is, and thats all that matters. Really any car isn't 'accurate' to the engine hp and torque due to drivetrain loss on a chassis dyno. But guess what its more realistic than measuring on an engine dyno, because you are seeing what the wheels are recieving, not what the engine puts out.

I'm curious, was this pull done in 2nd or 3rd? Numbers seem high-ish for a 93 pump auto car on a mustang dyno.

Anyways, very nice car to the OP. Enjoy it! I love the auto myself, its much better than any 5 speed
