Sounds like you have a good tuner but I only asked because if the injector latency's were off it would cause the same type of issue you are experiencing. Sounds like he's on the job though.

I'm not sure if you can disable the rear O2 completely in RomRaider like you can ATR. I thought I read somewhere that there was a definition created to do so but I'm not sure what open source software it was for. Otherwise ATR is the only one that I know of that supports disabling the rear O2 fuel trims completely. The rear O2 is highly inconsistent on non stock catted cars and has the ability to affect short term and long term fuel trims. Cobb recommends disabling the rear O2 sensor in their advanced tuner guide.
