if u buy a used tuner and its been pretuned, do u have to use the tune it already has can it be reset and retuned. or is that more trouble than its worth?

 

A used Diablo Predator - no problem. A used SCT XCal 2 -it will have to have tunes re-loaded on it specific to your ECU code. A replacement SCT mail-order tune filefrom a reputable shop like VMP Tuning isonly $50 though.

 

I had a question relating to the SCT Xcal 2... I just had 3.73's and posi installed on my '96 (w00t) however my speedometer is off by approx. 7-8 MPH and my odometer is going crazy; I read something about how the SCT Xcal 2 can only re-calibrate the gear ratio on vehicles 99-04. Now I want to get the tuner anyway to get some xtra horses, but I was wondering if anyone here has experience w/ resetting the speedometer for my year, or at least point me in the right direction on who to ask about this.

 

Automatic or manual?

E-mail Justin atVMP Tuning and ask him if no one on hereposts ananswer.

 

yea... if u go to mustang tuning the tunes are only 25 bucks... they email you the tune then u can load it up on the sct
