I ran a stage 3 cobb map on my Evo and my AFR was the same. The AP AFR is not accurate. If you would like to properly check your AFR get a dedicated wideband. Another way is to pay for evoscan and buy the tactrix cable and check what it's logging via mode23. Your AP enables mode23 by default but once you uninstall it from your car it will be disabled.
I ran stage 3 in 91oct for all of 6 months and practically babied my car and driving home one night, the car started to studder. Checked my spark plugs, the one is bank 4, had blown the the tip off it. Luckily there was no damage.
Do yourselfs a favor and get a proper tune, I'm not bashing the AP but I feel much safer now with a protune.
