I find it easier to blend since I have E85 available and is cheaper then race gas.
You need 30% ethanol content, so do the math and fill your tank accordingly. Make sure not to have less then 30%... Log once you load the map to make sure all is good.

+1, though i have never tried 100+ or E30 MAPs

It looks like the E30 map might more power than the 100 octane race map? It would definitely be cheaper to blend E85 with 93 octane but I didn't know our fuel system would be able to handle it? I am FBO and completely catless. I guess, should I run the E30 map and just try to run about 1/2 E85 with 1/2 93 or should I get 100 octane and add some E85 to it and run the race map?
I know I could get a custom tune later, but I want to try something today  I may go dyno this week as well to see what kinds of improvements everything makes. My new wheels are about 10 lbs. lighter than stock (and still 18's). My last dyno on aggressive + FMIC (302) was 387 rwhp and 423 rwtq on the stock wheels.

Yeah, you should love the E30 MAPs. Without an ethanol sensor, it is tough knowing exactly what the % is. Based upon E85 being 85% Ethanol and 91/93 USA Octance being 10% Ethanol, you should put about 4.5 gallons of E85 pump and 11.5 gallons of 93 or 91 (full tank). Use this calculator

Remember, USA octane is RON+MON/2 = USA Octane, thus E85 is more like 96 USA Octane and of course 91 or 93 is 91 or 93 USA Octane.
Make sure you log some good 3rd gear pulls and see how your car responds to the E30 MAPs.
