i just bought a boat with twin 6.2's with prochargers, anyone have experience with prochargers in this application? The boat runs like a bat out of hell...BUT, it seems to be running rich at idle. Fuel pressure guages read 28-29ish at idle. They smoke at idle and when docking you can see what appears to be gas floating around the transom. I also can smell gas in the oil.They put 130 degree thermostats in when they installed the units. Does anyone know of a shop or mechanic in VA who has experience tuning while the boat is running at different rpm's? And what should the fuel pressure be at idle????
