Turbo cars are suppose to run 11.0-11.5 AFRs to be safe.(or you need to look into timing/pcm control) I have one
Almost any aftermarket engine (or exhaust)piece is considered a "race part."

And its blue smoke, which is burnt oil.

On a side note: Mx6GT89 you may want to do a compression test on your car to be on the safe side.
