No, first pull (#4) was 91 octane in December, 2nd (#13) and 3rd (#15) pull were yesterday, so it added 20+whp over 91. The 1st run 91 octane, 2nd run 94 octane and Meth, 3rd run 94 octane / E85, ~80/20 mix. You can see in the 2nd run the AFR's go pretty rich do to the Meth, probably set a little too high, but it still made really good power. Personally I would not add E85 to a VT2 kit, unless you are monitoring it and know what you're doing, it leans out the mixture quite a bit, and the stock fuel pump is at it's limits with a VT625 setup, especially in cool weather.
