Check Engine light codes
Hello all, I'm posting a list of codes I have retrieved from my 00 corvette FRC. I recently had to replace the wiring harness to my IAT sensor and install a new IAT sensor as it seemed the wire was cut to it. I cleared the code for that and it ran fine without codes for a while until recently it threw another check engine light. I bought the car with long tube headers and I believe is catless, but not 100% sure. It had the loudmouth exhaust when I bought it and a god awful spoiler that I've since taken off and put on the stock mufflers I got for a really good price. Here's the list.

I appreciate any help you guys have with this. Hell, I guess it might need a tune?
edit: also, all FRCs are manual, including mine, so why do I have that transmission code?
