buying used 5.0 and i need help !

Beware, if there IS a tune in the car and you bring it to the dealership you could have an issue there.

I recommend calling the guys at SCT and asking them how to check if there's a program installed on the car or not. It's probably very easily found in a menu on the device or by taking a read from the car and sending it to them.

I'd do that before bringing it to a stealership.

I called sct already but they told me that there is no way that they could tell if there was a custom tune in the car or not....

I already spoke to a dealer that will look at the car and give me info on the warranty on the car and all that good stuff so well see what happens...

The skipshift is a really good way to tell if its tuned or not...good idea...thanks

from experience tune or no tune all car companies will try as hard as they can to not warranty your car no matter what. they are in business to make money, doing free work does not make money. plus there is a tsb from ford to there techs to look out for any mods done to the mustangs. also i would like to bring up unless your buying cash you might want to look at the interest rates for new and used cars, you may pay more for new but the payment may be the same because you can get a lower interest rate on new

I bought a 2011 GT last August that I knew had a tune on it due my expiriences with my tuned '05 GT. I didn't like the tune the guy had on it, so I just went into my local Ford dealer one day and told them the truth. I said I had bought the car used, that I thought it had an aftermarket tune on it and I wanted the ECU returned to stock. An hour and a half and $100 later I drove off with a stock tuned car.

I really depends on how your dealer deals with these types of situations.

"I bought a 2011 GT last August that I knew had a tune on it due my experiences with my tuned '05 GT"
Thats a pretty vague explanation as to how you knew the car was tuned. Can you please elaborate on how you knew it was tuned before having a dealer scan the ECU?
"i need to know if the car has a tune or not"
That is the OPs original question. It was my understanding that a scan with dealer equipment was the only way to know for sure.
