1. Run the new e85 map with 91 octane mixed with e85.
2. Continue running Stg 2+ aggressive with 91/e85 mix.
3. Get a protune 91/e85 map.
4. Run e85 map with 91 octane and meth
5. Get a protune map for 91 octane and meth.
Thanks in advance.

Speaking from experience and using what I learned on the dyno with my tuner, you can NOT beat a good protune for e50 (50 e85/50 9xoct). I can only imagine how good the results on a meth/e50 tune would be.. ultimate track setup. I can't bear driving my car on stg2 agg anymore when e85 isnt an option (its 25+miles away). When the difference is this significant (330whpish vs 450whp) it is a no brainer for me. As far as fuel consumption goes I have lost maybe 1.5mpg on the e50 map I have, however it is a very aggressive tune so if this is a concern for you i'm sure if you just tell your tuner your goals they can adjust accordingly to make sure its not a complete gas guzzler.
