Re-calibrating The Speedo Here in the next week, I will be installing 4.11s/true trac in my T/A going from 3.42? Maybe?
Obviosly this will throw off my speedo, it's a M6 car so thats all it will effect. In my truck I was able to just change the worm gear in the trans to compensate for the larger tires/deeper gears.
I'm assuming that I will need to buy some kind of programmer, or have my car tuned to correct the speedo?
BTW, it's a 1999.
Thanks,
Chris
