I'm needing help selecting an upper pulley to for my new VMP 2.65 Gen3R setup. Street tune will be on 93 octane and I do not feel like playing the Torco additive game. My current lower is a 4lbs Metco lower (I'd prefer to keep the lower but I am willing to install a different lower for the right combo). The fuel system will be a return style setup with two 485lph pumps with ID1300X injectors. If it matters the exhaust setup is Kooks 1 7/8" x 3" long tubes. Any help is greatly appreciated.
