What octane scale? Is 95 the cheap gas? You want to still run premium with E85. If you ran the cheap gas (our 87 octane) with E85 I wouldn't expect to see 17 psi on a 50% mix. You can add more E85 to get more boost. Try a 40% mix if your trims are good. Also the learning happens after 4000rpm at WOT in gear 3 and 4. Make sure you do some wot blasts there.
