2007 GT500

Have a 2007 GT500 that I'm trying to load a tune in from a u7145. I go to program, select the tune, tells me its going to download the ori, turn the key off, 3 sec wait, says turn the key on and I do, but it stays on that screen.
This car is a customers and its SVT and I believe its got a smaller pulley, but not the 2.7. Could it be it has a tune already in it which is my problem?

Thanks for any help

no, it is probably defective as it is not sensing the key on properly. First try another U7145. If that also doesnt work, then check to see if any aftermarket electronics are installed and interfering with the communication.

Not sure about using the wrong pulley with their pulley tune but I would bet you will need a custom tune for that setup. If he has a tune already on the car, the predator would give you a different error message indicating that and you would need the vehicle flashed back to stock before the predator can read the vehicle.

concoursd is correct, it's probably just a defective unit. After all is said and done, if you want a custom tune, let me know and I can take care of it.
