Great info thanks. my case, its A10. Best best bet would probably be sticking with street set up.I had this discussion with Roush about going to a bigger tire. It’s not about the speedometer being off a bit, it’s the 10R80 transmission will be shifting improperly if they don’t change the tire diameter. They said if you have a manual transmission it only would affect the speedo a bit.
Btw, in 1st gear. mine won't shift to 2nd untill it hits 2k rpm( driving slowly after a cold start). Is it supposed to be shifting like this?
