Not too bad… o i believe it can be done. just not on the tune i have now, not sure if the fuel being e98 containing 13% more ethanol has anything to do with mpg’s Beings that you have to add 30-40% more fuel for e85 i would think e98 would be more like 40-50% more fuel than petrol. Plus as always Evans tunes are way conservative. on the other hand your car has to be a beast at 40psi. How does your drivetrain like it? What turbo are you using? > [@Audiophiles called out](https://forums.speedlife.net/t/audiophiles-called-out/41090/47): > > Well my tuner is a bit apprehensive to give me the green light to run E85 in my car at 30 psi. If that is b/c very few guys with a 2jz are doing it or b/c he doesn’t trust whether I’ll be getting a true E85 mixture (as opposed to E70) or whatever the reason he has, I’m not certain. He’s one of the better (AEM) tuners out there, so while I question him to gain knowledge, I also don’t doubt it either. As previously stated i bought my fuel from rockett brand race fuels it was $450 shipped to my door for 55gal drum. They do make ethanol test kits that measure the amount of ethanol in a batch of fuel. If you are going to be daily driving your car i would not reccomend switching to ethanol. If its a weekend warrior at the track and on the road its a different story. --- _[View the full topic](https://forums.speedlife.net/t/730whp-460ftlbs-27psi-on-e98/202808)._
