Jeff This car use to be fuel injected and it still has the high pressure pump in it with regulator to knock down the pressure. regulator is set at 7.5 lbs also we dyno'd the engine and it still has the same power from when it was built[/QUOTE]

If the engine ran good on the dyno , then what parts are different between the car and the dyno ? Usually the dyno has it's own ignition box and it's own fuel system . Maybe check these two systems out to start with .
