Im not blaming mpt for anything just wanted to see if anyone has come across this. I put my stock tune back on my car because Im taking it back to the dealership for the weatherstripping around the corner window starting to come off. Also, the ac hasn't been blowing as cold as it used to along with the blower surging. You can feel the ac blowing at different speeds. Also my brakes squeak along with my belt. So I put my stock tune back along with unplugging the battery for 10 minutes. Now my ac is blowing so much colder and gets colder quicker and no longer surges. Even my car voltage stays up higher. I have a radar detector that tells me my voltage. Could it because I unplugged the battery? It's really confusing.

But then again, I've unplugged my battery many times before and it never fixed the ac surging.

Are you throwing any codes? Looks like you're still having issues after the "tires not spinning after exhaust thread". Call up your tuner and tell them what is happening so you can send them a datalog and have them try to address your problem. No need for guesswork. Any good tuner will be glad to check a datalog and see what is going on there so they can make adjustments or point you in the right direction on what needs fixing on your side. The stock tune (especially with your mods) should not be outperforming your aftermarket tune unless there is something wrong on your side (*IE a vacuum leak etc.) or adjustments your tuner needs to make on their side. Good luck and let us know what was the cause when you get the problem solved.

Since you unplugged your battery, maybe what you're feeling is your ecu relearning. Anytime I've unplugged my battery on any car, they always seem to run a lot better and faster. Then over time it becomes less peppy.


Good luck with your rear quarter windows, hopefully you have less of a nightmare than me. Those windows have all kinds of issues with the trim.
