Hello,
I am running a Holley 4DI (aftermarket carb to FI conv.) kit. It is now called the commander 950 system. It is a throttle body and bolts to intake manifold like carb. I am running on a 542 inch motor and must tell you they at tech. service were worthless in terms of helping with fuel map for the engine size. I have made all my own maps and will email to anyone who needs them. It is a great stand alone system and the difference from carb to injection was unreal. I also bought software to allow real time observation and tunning that I feel was the key to sanity.
