My 06 MR is untuned and one night decided to turn my boost up to about 24-25 PSI using greddy Profect II. I did a first gear roll and when going into 3rd I misshift and didn't get it into gear then stopped. A couple mins after that my ECL popped on and the car would bog when I give the engine any load, hard to go up hills. I changed my front O2 sensor and reset the light, also changed out my plugs. The o2 and plugs were really fouled out. Once changed the problem still exist and code comes back, I also tried to reset my ecu. Do you guys have any other suggestions?

You just answered the problem in your story. Untuned. Just get a car tuned, it will fix everything.

I already turned my boost controller off and it's back to waste gate psi. But the problem is still there. Any ideas?

I had a simular problem and found that I had a chafed O2 sensor wire. I repaired the wire and it fixed my problem. Hope this helps.

How did you chase your o2 wire? And do you remember where it was chaffed and how it happened?
