I would think if you're running an OBDII reader like Torque Pro app, you can tell by your AFR. But one time I tried logging 2 pulls, 1 with 92 Fuel Standard and the other with 92 Fuel Out, and my AFR seem to be the same. I'll have to run more test when I have the time.
btw, I did get a P0102 CEL (MAF low voltage fault) running 92 oct All Drop-in Filter map with Timing Standard and Fuel
Out. This was just having an Apexi panel filter (everything else is stock).
