BTW those BBS look excellent on your car.
I am on the stock fueling system. You will not get any mixture codes if you are properly tuned. The only times I have gotten mixture codes is when I have had a few gallons of E85 blended with 93 on the OTS 93 pump map.

If I were you, I would wait until you have your bolt on mods complete before you get tuned so you don't have to go through the process again.
