Greg....if you can find any specs on Sunoco fuels, look for the RVP (Reid Vapor Pressure) and specific gravity to make adjustments. I've had no luck finding data on Sunoco fuels although it must be somewhere.

VP's C12 is more dense and higher RVP than C11 making jetting down necessary. Also,if you choose C11 and run it through the summer, try a cool can with it...,you'll be surprised.
