Was hoping someone could give me a clue as to what's going on with my car. I have a 2011 mustang GT auto. I got back from the shop last week after getting long tubes and off-road X pipe installed. On the way back the engine light came on. Pulled the code, it was cat related so I figured I'd put my new tune in. I got my SCT tuner and installed my bama tune. After the new tune was loaded, I shut the key off, and then started the vehicle. After a few seconds the wrench light came on. So I reinstalled the stock tune figuring maybe it was something wrong with the bama tune. Wrench light is still on with the oem tune. I did a visual inspection under the hood nothing looks out of place, throttlebody wires don't look like they've ever been touched, still plugged in tight. Air box cover was on properly too. Besides the wrench light I have some other symptoms. Doesn't feel as fast as it used to(maybe I'm getting used to it), and at wide open throttle in second gear it redlines early at 6000 RPMs and will not shift into 3rd, it will just bounce off the rev limiter. Any ideas would be appreciated, thanks in advance.
