TwEECer has a tuner for your car. Not too sure if I'd recommend it, I've never had any experience with tuners.

Just putting it out there.

I`m not sure why my car has OBD II,it was built 06/94,but it has it.What "other things" am I going to need?I have a bigger diff,5 speed tranny,rad,factory dual exhaust for a 5.0,1 complete running `92 T-Bird.Send me more info,this project is ready to start at any time.

TurboLX · July 5th, 2007, 08:48 PM

well your gonna need a set of motor mounts

and im not sure about this, but i think you have to change the K member as well

1FastMustang · July 7th, 2007, 04:38 PM

Does anyone know if the K-member has to be changed for sure,I don`t want to start hacking this car up,it is a rust free never damaged mustang,just needs a little more power.And I know some say to buy a GT,but this car has never been abused and it`s paid for!
