Well she's back. The culprit for the CEL, according to apm, was the avcs solenoid. It was replaced and there was no longer a CEL. I've since driven the car quite a bit, carefully, checking for smoke, sound, loss of power etc. Also monitoring the AVCS too. I also purchased a AP and have datalogging the car and from doing some research on how to read said datalog I don't see anything of note or alarm. I put the car on stage 1 and will probably purchase a downpipe in a few months. I'll be getting the banjo filters removed soon as well but I need to check with APM about it since I took it in with it in mind that they'd be doing that. Everyone is very busy and I still don't have the tools yet in the garage to do the work myself - believe me I want to.
Of course I'm still paranoid about the turbo but apm stated there was no signs of the turbo failing. It's in very good condition for the year and mileage I guess. Except for the solenoid which has been taken care of. I am actively monitoring the knock, DAM, coolent Temps etc when I drive.. Hope she stays good till I get a turbo next year. The previous owner even helped me with some of the repair costs which is very nice of him. I've taken into consideration everything that was said here and I will be diligently maintaining the car and monitoring the oil all the time for signs of metallic particles etc. Thanks everybody
