Lucky me, time for California emissions testing! I have the Predator canned "performance tune" currently installed. The only modified parameters are for gears and rear O2's disabled for my o/r midpipe. I'm having my factory midpipe put back on and will re-enable the rear O2's. Now I know that technically the Predator is not legal here in CA, but what I'm wondering is if smog testing equipment will detect the tune. From what I've been able to find out so far, only Ford dealership equipment is usually capable of detecting aftermarket tunes, but just wanted to make sure.

 

You should be fine. As long as your rear 02s are on you should be GTG.
