I just ordered Richmond 3.73's and I now need to find a method to recalibrate the speedometer. Hypertech programmer is what I was looking at, just because I was going to go with 2 of my friends who have 96 and 98 GT's, but I read that it will only work on one car and not others, is that true? I'm not going to spend 300 dollars on something that recalibrates my speedometer with little HP gain. I have also looked at the Dallas Mustang Speedcal, but 100 bucks still seems kind of pricey and I have no idea how you wire it or anything... does anybody have suggestions, i'm not looking to spend over 100 bucks.
Thanks
Thanks
It's a good product with excellent customer service behind it. Get the SpeedCal. 5 speed or auto? I'm assuming the former.
