To add more info on this. I checked my CEL codes yesterday because of the downpipe. I had 2 wastegate codes hidden in there. They didn't cause the light to go off, but they were there nonetheless.

The codes I had were for wastegate learning: open too far and one just said fault. I also had MAF: too much air because of my aFe intake and of course, cat efficiency too low from the downpipe.

Only the downpipe caused the engine light to come on, but those two wastegate codes concern me. I'm counting the days until my wastegate pukes.

I'll try to post a picture of my print out when I find the piece of paper.
