is there a difference in 05-06 gt tuners and 07? could i use an 05-06 tuner on my 07?

 

they are the same! But you would obviously have to get a new tune.

 

What do you mean exactly? You have seen handheld tuners for 05-06 and then a different one for 07? If so I would look until you found one for 05-07. Here:

Brenspeed

This is a tuner for the 05-07 and they also have great custome service.

 

There is a difference between the 05-06 & 07 electronics.
Predator is two different part numbers...U7140 (for the 05-06) and U7145 (for the 07). I think Brenspeed will ask for you PCM code to make sure you get the proper SCT tuner.

 

Thanks the dealer told me only sct did one for 07 i was just curious
