I just had 4.10 gears installed on my 06 GT and can't wait to reprogram car. I reprogram as per instructions and the car will not start. Any help would be appreciated.

 

I would have to say first thing would be to put it back to stock and make sure it is the tune and not the car. I know it was running before but you never know. Then go through the procedure again. Then if it doesn't run call the tuner maunfacturer and I am sure they can get it fixed for you.

 

Try changing just the gears on the stock program. I think an SCT-2 will let you do that.
