Which map for E30 in m235i F23 RWD Vert

I have loaded up with E30 after testing the E85 ethanol content and using the E85 Mix app to calculate what I needed to put in the tank.

I'm running stage 2 (Active Autowerks catted DP, VRSF intercooler, boost and charge pipe). Now I have the E30 in the tank, I loaded the BM3 Stage 2 E30 program (had been running the multimap on map 3 for 93). I can't say it felt like I had more power - in fact it honestly felt like less. After playing for about 25 miles I switched back to the stage 2 93 map and it definitely feels stronger than with the E30 map. I'll wondering whether the multi fuel capability of the stage 2 is helping somehow even though the car doesn't have an ethanol sensor?

Am I missing something (it wouldn't surprise me if I am - new to all this). Thanks!

post some WOT logs of both and we'll be able to see what's going on.
