but what you can do is buy a speedcal from brothersperformance.com or dallasmustang.com OR send your ECU to someone like T & J Performance and get them to reflash your ECU for you.

I wish i had gone with 3.73s. 1st and 2nd are just too short for my liking. Good luck and have fun!Bob H said:The car pulls alot stronger in 3rd & 4th gears but I really haven't put the pedal to the metal since I only have 300 miles on the car. Just putting all of the peices in place for the KB 9psi supercharger in a couple of months.
Why is it that the 96-98 also has the EEC V computer, but you can't fix the speedo the same way you can with the 99+?Bob H said:I had the local Ford dealer install Ford Racing (3.73) gears in my 2003 GT today but according to them they were unable to change the computer to reflect the new gears so the speedometer/odometer would read correctly. I know many of you have changed the gears and I thought it was a simple computer adjustment to get the speedometer to read correctly on the 99's and newer. Please let me know what I need to do and who I can take it to.
the 99+ GTs have an electronic speed sensor. the older ones had a gear/cable driven speedo.Black96VertGT said:Why is it that the 96-98 also has the EEC V computer, but you can't fix the speedo the same way you can with the 99+?
Bro, you are going to wish that you kept the stock 3.27's with the KB. I almost went with 3.73's also, but I am glad I didn't now. Traction will be a serious issue for you. PM el_kid_1 , he has the KB 9psi and the 3.73's. IMO the stock 3.27s are perfect for the KB.Bob H said:The car pulls alot stronger in 3rd & 4th gears but I really haven't put the pedal to the metal since I only have 300 miles on the car.

Actually, from 96 and newer they all have electronic sensors. The difference is where the electronic signal goes from the sensor in the tranny. For 99-up cars the signal goes directly to the computer and the computer controls the speedo / odo etc. functions. For 96-98 the signal goes from the sensor directly to the speedo / odo cluster and thus is not controlled by the computer.Dan_Soprano said:the 99+ GTs have an electronic speed sensor. the older ones had a gear/cable driven speedo.
