I'm in CO....
I know bro, hard to believe... No way in the world did I expect 100 hp from fuel, tuning or not. Now that I do think about, although the commanded timing wasn't changed, I believe the datalog said it was adding a degree of timing over what was commanded. It wasn't pulling any on pump, commanding 17 and seeing 17, but I believe the first pull on e85 was 18......Still that's not a huge factor in the power difference. Even with 4 more degrees of timing, it didn't pick up alot more power relatively speaking....
a 100hp pickup from 91 should be expected. we picked up .7 tenths going from 9.99 to 9.27, and that was running ms109 unleaded race vp
huge difference
