Where's Jim, i want to see his car's tune on some straight E70 and see how rich it gets and if it knocks at all. I know Shane tuned him on spring blend for afr of like 11.3:1 or so, and then on the summer blend he was up to like 11.9 or 12:1 afr, and then back down to low 11's on the fall blend...if he runs 10.7-10.8:1 afr on the winter stuff and is able to run the same amount of boost and timing w/o knock, that would be really cool!

I had a "E-85" evo on the dyno and we switched gas stations.
Car moved .7afr instantly and I had to pull 5+ degrees of timing just from the octane change fun stuff.
Brownman was on the dyno with the 61, him and john were tuning the dsmlink, and got marginal gains, they are contributing it to the fuel.
E-70 isn't very high octane at all considering E-85 is 105 octane tops.
