WTB: programmer to correct 3.73 gear / speedo

anyone have one?

the only one i know of is hypertech.

If anyone has one they want to sell or knows of a link to find one for sale,
please let me know.

thanks

I have a hypertech, but it doesnt work anymore.
I got it with the car, used it once, worked good, went to make some changes, and its shooting off all kinds of errors.... BS!


I wouldn't mind if the programmer did fan turn on temp, rpm limit, speed limit, shift firmness, shift points, etc.
