I to run e-85 has been a learning curve over 2 years, as stated it will like 1 -2 more degrees of timing you can play with squirts and cams ,but one of the huge gains I found was changing plug heat range (ngk)from 8 to 7s just a thought. Mark sullens worked with me on the tune. I don't know if you recall I was trying to get the 1250 in tune finally switched to a 1050 went from 9.90 135 -137 to 2 weeks ago 9.63 142 mph I still have a convertor issue.as my 60ft is terrible 1.41- 1.46 just my issue check your plug heat range AL... I stage at 170 cross the stripe @ 180
