Hey BLKM3, I really think the key thing here is that you really just need to have the car running the way a gt700 was intended - in other words using the cats/exhaust. I know you like it loud tho
Having a straight pipe without any cats is leading to a bunch of 02 codes (a la p0171). Want to try the car with some cats and the normal software (remember yours is different to combat the overboost with no cats)?

My car was running fine before. I ran leaded fuel with the previous plugs, but no leaded fuel on the current plugs.. Will adding cats give my car more power, because I have back pressure??
