I really want gears for it bad. Talked to the service manager and as long as I don't flash the ecu the rest of the drivetrain will still be covered. Thanks for the help. I did a search and have read every post in this section hopping I wouldn't have to ask.

The speedo will be off. Other than that you don't need a tune for it.

The speedo will be off? Did they change the way the speedo works from all other F-bodies and vette's in 2010?

It's an electronic system. If you change the gear ratio without adjusting the computer the speedo will be off a little giving the wrong MPH reading.

FWIW, I have had 4.33's...3.70's...& now the 4.57 ratios in mine and it needed a recal each time. Good luck with those 4.33's. Mine lasted maybe 200 miles after the break-in.

My guess is that he will be turning about 2200 RPMs at 70 in 6th gear.

Like they said...just speedo off.

if the speedo reads off does it rack up mileage faster? I had mine tuned after the gear swap but I've always wondered that.

the only cars that don't need the file edited for rear gear changes are m6 c5/c6's... all others need a file edit....
