As for fuel, the Byrons 30/11 blend is great. The label will say Race Blend 3000 on it. I personally run prodriver 3000 but that is my preference. My Plus 4 Btt went almost 8 gallons before I even considered a pinch. I had it pinched and its my back up. Always preheat (great investment is the Comp Products heater) and tune the engine for performance not to temp (try to keep the temps between 210* and 250*) and it will last a long time.

The 2058 should run good on the P5, I like the 41021/2096 combo on my Nova Engines.
