Been reading up on E85 the positives HP gains etc. but also read that tunes are required often to achieve maximum potential. How often are E85 users getting tuned? Also is there any type of generic ECU mapping that would work as a reset in any way?

 

Get a conservative tune and you will not have any issues. If you are trying to have max power all the time then a tune every few months depending on when the blends change by the month.

 

Cool thanks for the information.

 

you could get an e-tune from a few vendors on here. if you want it safe year round i suggest telling the tuner you want it to be a bit conservative.
