In preparation for moving out west where there is no 93 octane, which option do you think will be the best option for performance and fuel consumption?
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.
