I have ahuge problem i got my 01 gt didnt know it had a tune untill after i bought it when i went to tune it myself. I cant tune itbecause i dont have the original tuner that stored the stock computer settings i dont know what any of the settings are any suggestions should i go get a dyno tune or what?

 

I would just get a dyno tune, It's also the best and most safe tune you can do to your car.---IMO

well go find who sold you the car, and see if he has the tuner.. they are vin locked, there would be no reason for them to not give it to you. if it is a dealership, claim that you didnt know the ecu was modified and want it returned to stock
