Then I had the ECU flashed by Technosquare. Now I'm getting P1283 codes all the time. Idle in P or D has been smoothed out, however, my RPM still "surges" when coasting downhill or towards a stop but only by 250 RPM.

even with UTEC or FLASHED ecu I believe it would still throw a code since MAF senses more airflow than normal, so computer will sense that "it's not getting enough fuel when it does"... i.e. F/I guys. They have their EMS tuned for optimal A/F ratio but still have these codes. I think as of now the O2 simulator would be the only fix to these or a black piece of tape over the SES light . Please don't quote me, these are simply my own opinions.

In my head, it seems to be a phantom code that does nothing to the way the car drives. Just comes on to alert you to a problem that doesn't exist. If your on Osiris, just have the code your getting disabled....problem solved...lol
