get a tuner with the right tune and you should be good to go.

just replace the speedo gear in the tranny. Takes about 20 minutes and plugs into the side near the tailshaft.

after looking at this thread and that oil thread it looks like 3.8Lmustang really likes to pay out the ***.

Thank you very much for all your input.

Do they make tuners for cars without the OBD II? since mine is a 94'?

What R3D said, I think it's a 21 tooth speedo gear for 3:73.. maybe referred to as "white"?

Edit.. 21 tooth is "red" .. whoops
