I used its sister fuel 113 and I wasn't patient enough to tune to it from the c12 that I was using prior. I thought the stuff sucked for the proclimations by the manufacturer. I had indications that it has potential but it wrecks everything rubber just like alcohol. The Q16 has more oxygenators or ethonol and should make 5 % or more power than C16, but the side effects of alcohol were not a pleasure in my expierence having used only gasoline for years. The epoxy in my hood scoop that holds my air pan delaminated from the fiberglass from the vapor from the 113. The epoxy was GM door skin adhesive and the vapor made it like puddy, No sht. Good luck with it, it is more powerful than strait racing hydrocarbons if you don't mind running alcohol. In hind site, I think tuning the fuel on the dyno would have probably been more rewarding on that venture. Field tuning was very evasive, and I'll have you know I like a challenge tuning but not one like that stuff gave me.
