Took the stang out this evening for the first time since switching back from the emissions tune to the street/race tune. On the frist WOT the thing skeert the crap out of me, rolling about 10 mph with a/c and t/c on and floored it. It took a deep breath then shot like it was slung from a catapult. Spun tires into 2nd and into 3rd then I let off the throttle but it just kept on going WOT I hit the brakes but the engine was still WOT. By this time it was well into the triple digits and I was like WTF! I tapped on the gas pedal and it finally let up. I tried it a few times after that with no issues. There was nothing in the way of the gas pedal. What happened? And best of all what do you do in that situation if it doesnt come off WOT? Only thing I could think of was turn off the key but then I would lose steering.
