I think with just a basic tune an E30 mix is ok. If your trying to get big numbers and have the latest and greatest tune like the JB4 G5 ISO with the BMS flash or the Proceed Rev3 with the flex fuel system and Shiv's flash then you can def run an E40 or more mix no problem on the stock fuel system from my experience and from what I have read. I have a buddy with the Proceed Rev3 with flex fuel and flash running 100% E85 and he isnt having any problems as of yet. But its only been about 3 weeks or so. We will see how long it will hold up in a couple months down the road.
Are you getting your E85 at a Kroger?
