Are you 100% positive that BAMA turns of the rear O2 sensors on the race tunes?
The reason I ask is because I always order performance and race tunes from BAMA based on 91 and 93 octane gas. I have aftermarket headers with cats. And my various tunes(I usually just use the race tunes) would cause a CEL and I finally had to specifically request for them to turn off my rear O2 sensors for all my recent tunes.
