I have had the car back for a few days now, everything is finally resolved. No CEL. The problem was a faulty installation; looks like BFI knocked a diode off the ECU.
5 months of hassle and I certainly don't have much to show for it. Lots of stress, lots of phone calls, and who knows how many gallons of gas I ate up driving back and forth to dealerships and BFI. Net loss for me.
BFI never did refund the installation fee I paid to have the car flashed....
Going to be well out of warranty before I consider tuning the car again.
