Were you locked up in third?

With a 1/4 Mile - 12.5 there is no way those numbers can be correct.

Never knew 03/04 Mach's to post big numbers on dynos (especially autos). Had a buddy who's stock numbers were like 238 rwhp but ran 13.3's at the track. I used to tell guys those fewer "horses" posted were Clydesdales not Shetland ponies. I wouldn't get too wrapped around the axle on this and be more concerned with how it feels and track times. So many factors like different dynos, different numbers, Mustang Dyno vs Dyno-Jet and etc. If you car's running good and feels strong, don't let it bug you. If it's falling on it face over 4500 rpms then start looking into it.

Bill is right....dyno numbers don't mean a ton w an auto....

Hint...It maybe youre tune ...Mach 1 automatics are very tough to dyno , Dan at Pro -Dyno had a lot of trouble trying to get my converter to lock up. That being said I had my car Dynoed at Pro-Dyno , Fastlane, Haywood and Staples . I was using a canned SCT tune at the time and the readings were almost ALL the same 285 HP / 305 QT.Each tuner that I talked to said they could NOT due better using a custom tune on stock parts.I decided at that point to add a few things and just use Nitrous to get the HP...360 and TQ...385 up at the wheels. Its just a street car.
The final tune on a Compucar 90 shot was done by Dan at Pro- Dyno using a custom SCT tune as stated in my sig. Dan took 6 hrs to due it since he was tuning the motor and the trans. The BEST guy to deal !

Those numbers look like a 2V swap lol! If your running 12.5s I wouldnt worry too much but definitely look into a new tuner, Bama suck!
