To take full advantage of E85 you would actually want a leaner tune.
Thanks! When you had HPFP problems, how much E85 were you running? And what type of tune were you on?

That's crazy that the DME can compensate for this.

I think I'd like to continue to use this 2 gallon blend just to up the octane to 93, but I'd also like to be tuned on this blend eventually. With a tune usually you have more timing and what not, would it still be safe to use 2 gallons of E85 with a 93 octane tune (91/E85 blend in tank)? No risk to the HPFP?

Thanks!
