Another silky smooth flex fuel car drinking that ignite E82. @cobbtuning has made it so simple to make a reliable daily driver ethanol friendly which is flexible to pump gas as well without changing the map. The most common question we receive is can I run 93 mostly? The answer is yes, when you do visit an ethanol pump it’s pour and go +50tq/+50hp like this 2017 WRX STI over 93. Huge gains for not alot of money compared to a big turbo or engine setup.
