Rich I took a can of VP 103 Uhleaded to the dyno when Jack helped me set up my VEC 2. We upped the timing starting at around 2500 and added one degree total at 5600. No difference in the numbers from our best program on 94 octane. In fact the notch cam back.
PS: the track tells me they have Unleaded race gas in Columbus.
