Received my e30 tune on Monday and going from a stock car to this is crazy. Besides the power increase, I also can't believe how much better the car drives. MPG is better as well on the highway.
Quick question, since the actual ethanol percent varies on my local 'E-85' due to seasonality (label says 55-85% ethanol), is it ok to put 6 gallons of it in instead of 5 with each fillup (the rest with 93 octane) to be safe?
I know the E-85 increases the octane but I'm not sure of the drawbacks of adding more E-85 in relation to 93.
Thanks!
