ok waiting to hear back from Allen but i confirmed my IAT is about 77 degrees and my ECT is 180 degrees. Swapped the O2 sensor and still same thing.

With the small turbo it goes into boost very easily so it goes into open loop quicly and immediatly rich.

Allen just worked on a retune and got my wideband back in line where it should be. I did scan the other day and saw my long term fuel trims are wacked out so I am going to check my o2 sensors again and see what is up. It is strange only one side was bad and since it is a front mount turbo the exhaust should be the same I would think. Maybe a sensor.

Ours gave only one bank running rich as well bank 2 i believe. I heard that on the 2010 trucks i think u have to reset the o2 resistance values or it will fry the new sensors didnt do that last time we replace them. Its getting worse so ill hook it up to the scanner tommorrow and see whats up.
