what kind of deal do you want to work out and is the tuner set back to original?

I have a U7145 that is no good to me since the guy i bought it from on ebay sent me the wrong one.I need a U7140 perhaps we can work out a deal and trade them?

It says the last tune written was original backup

I bought this tuner form ebay about 2 years ago it was new i plugged it in to my car and the battery was almost dead it ended up screwing up my pcm. I was scared to plug it in again after i got the car fixed.so anyway i plugged it in yesturday and now it says my vehicle is not in our data base ...

I have a 2005 GT and i lost the computer in the car and now with the new computer in the car,when i plug the predator in it tells me the calibration ID is invalid, Is there something i can do to fix this problem.
