I did this as well. Ran it for about a year, before I got tired of having "fill-up anxiety" due to 8mpg and limited e85 stations around town.I’m on a completely stock fuel system making around 540whp NA on E85. Also tuned by Lund.
Im in the process now of getting a 93 tune and flex tune setup so I can go anywhere. But the car is mostly on e85I did this as well. Ran it for about a year, before I got tired of having "fill-up anxiety" due to 8mpg and limited e85 stations around town.
yes, I ran the flex tune for about a year as well. When I realized that I had not filled up with E 85 for that entire time, I ended up changing over to the 93. I keep thinking I’ll go back to E 85 for the power, but I never get around to it. This car has excellent power on the 93 tune, which is probably why I have not prioritized E 85.Ye
