my speedometer and odometer are off now because of the 4.11 rear end gears i put in my 2000 trans am ws6 6 speed. i am not sure how to fix this without buying a 300$ computer programmer. is there a VSS sensor on this car i could just replace to get both the odom and speed to read correct? if so where can i get this at? any help or advice is greatly appreciated!

you need to find someone local with hptuners or another tuning program....i paid full price for a tune when i got my stall converter with the understanding all retunes would be free as long as i paid for the gas for him to drive down. Tuned again for the cam, and in about a week to tune for gears and an injector swap. you need to find a set-up like that.

You don't even need to find someone with a tuning program, any decent handheld tuner can do the trick too. A lot of people have the handheld tuners, I couldn't imagine it would be too difficult to find someone local with one that would hook you up.

Handheld tuners are tuned to one vin number at a time, so to get a friend/another local to do this they have to give up the use of the handheld on THEIR car completely in order to change another vin. The previous auto must have the stock tune reloaded to "unlock" the hand held.
Once done the handheld tuner will be locked into the other guy's car and is then usless to the previous individual.
