not ford

The car is probably idleing really bad. If it is your vaccum is too low and the ECU is having hissy fits. The Ford EECV is very sensitive and if that is the case it will get most of you low down power back. A significantly larger cam will always lose low down power though.

INJECTED250

Change diff gears to 3.7's...... easy burn outs

Hey Gino sounds like a familiar story to me too.

Its the cam and the std ecu combination for sure.

A custom tuned Chiptorque should be able to fix it.
