3rd run on the brand new set-up netted 768hp with PDR 370inj, @ a mere 65psi of boost. Only running 20degree's of pump timing and runs where made on a mustang MD 1750 dyno. Was also using water inj to keep things cool. Not bad numbers for a set of $400 injectors? Many thanks goes out to Piers for his technical support over the past year and numerous other people who know who they are.
