I have been having nothing but trouble with my tune...runs rich then lean then rich again and no one locally can tune it. Any ideas on how to convert to a newer pcm that can be tuned?? Please help!!

I bought a 94 PCM and harness, then got a stock SD M6 tune. The 4L60 runs the TV cable so then the PCM wasn't looking for my A4. Or you can also put a MAF in and not run SD.
