Hey guys, I'm back after a 9 year hiatus from selling my 06 vista blue GT. Picked up a 2005 GT stick in mineral gray w black guts. Has mufflers and a cold air open box similar to what you'd see on an 08 Bullitt. I noticed a 91+ octane sticker on the gas cap leading me to believe it could have a tune on it or at least did at one time. However, the guy I bought it from did not tune it nor did he receive a handheld. So question is if there is a way I can find out if it's tuned. I want to order a tune eventually and I don't want to find out it's already tuned where I try to upload my new one. Thanks!
