Fuel injection? Open or Closed loop?

Darrel, you have not had problems with Sunoco passing fuel check? Maybe it's better now. I tried that stuff when it first became "the official fuel of NHRA", to prevent hauling fuel in my trailer. Saftey issue. Lost two qualifying runs, at two different races. Bought the fuel from Sunoco at that track. Maybe it's better now.

C11, in my LT1 SS car, runs the same times between 12.8-1 and 13.0-1. Maybe half a MPH faster at 13.2-1 above 7500. I use Speed Density mode, Open Loop.
