I had a tune done after a head cam package and the tune was ****, it was running lean, caught it in time, and I was told, "the first tuner turned my O2 sensors off and all the O2 codes and set her lean." The guy who did the second tune once it was done it ran great for about a week, turned the O2 sensors back on she had great power, and now when I turn on my AC if am at operating temp or not it will turn off in the most inopportune places like a street light down town traffic .

It runs like **** at operating temperatures, I can feel it misses every so often. Any one have a clue. I was told to re tune it yet again and change the plugs before tuning, because the the plugs might be fowled. The thing is that I am tune stupid and I don't know what to look for when some one is doing a tune. I know I cant learn in here but what are some good things to look for what are some red flags when some one is doing a tube. thanks

well if it was running lean, it would be a good idea to change the plugs. i bet they got cooked. see if that helps. if not have your tuner log it and see what is going on when it stumbles or dies.

Yes the best thing is to retune it but with a reputable tuner. It appears you will have to do a mail order tune being that you are not really close to any good LSx tuner shop. The people you went to sound like hack jobs.

The best person for this is Charlie at RPM Motors Inc in California. He is the best mail order tuner ive seen that can tune the car remotely without driving the car itself and it will come almost perfect as if he had it dyno tuned. (By "almost perfect" I mean it may be off 1hp) All those driveability issues will be history for sure. You will need to send him all the info about your car (list of mods, cam specs, etc), along with the PCM.
