Premature shifting A4. Please HELP!!!!
Strange Problem... PLEASE HELP ME....
I had my car programmed with ls1 edit by a perf shop in arlington. Now sometimes the car runs great, and sometimes the car will shift prematurely. For example, I will shift from 1 all the way through 4 th within 2secs and under 20? It will shift correctly under WOT, but partial throttle shifting works sometimes and sometimes it doesn't.
Another point. When the premature shifting begins.. within 5mins my car ses light comes on and when I check the codes it says both O2 sensors have low voltage, and throws a TPS error?
Can anyone help me?
Why would it run fine sometimes and then sometimes shift like this?
Thanks in advance, sorry for the long post.

Since this has happened I have replaced the TPS and taken the car back to be reprogrammed. We drilled my TB and the AIC count is perfect, So I know the TPS sensor is not bad? Could this have something to do with me removing Torque Management. I never had the problem before the car was programmed. It seems like this happens to me about once a week and is really annoying. Can anyone Help???
