Hi guys/gals I have a 2000 ram 3500 5spd new vp44 new fass 150 and new 100hp injectors. When I release the clutch when starting up a hill or just slightly lugging the engine it surges like the fuel rack on a older mack . It also does it when I'm lugging a hill but this problem didn't happen till I put the new injectors In and I'm just wondering if this is normal with bigger injectors or do I have a problem
