(removed the 307 differential and install a 327,, install a newly retuned tcm ,, working out a few bugs , so far it works just like it was made for the car.
going to the track this weekend
did not open it just sent the 307 diff. with wavetrac to Untrax for R & D .
cost of everything
327 diff 400.
wavetrac 1200
installing wavetrac into 327 housing , then into car, tune the tcu,,, priceless,, )


Jim maybe I am mistaken but I thought the 327 gear could not be used on a car running the srt6 tcu and visa versa with n/a tcu and the 307 gears. I have the complete drive train from the srt6 in my n/a. I would rather have the 327 gears if the tcu wouldn't act up with the diff ratio. Rudy informed me it wasn't possible to run the n/a rear with the srt6 modules and engine. What have you done to mitigate the running of either gear ratio with your setup?
