Mine loses about 425 lbs with a brand new pump and old injectors. It is a very easy test to do if you have insite...check out Rawze's you tube of it. Remember to warm the truck up first.

Swear Rawze said 100 when we ran mine.. He could have said 4100.. Truck was running at the time and my 1939 was dead so we were plugged into the engine harness, with the hood open. My 2250 only lost about 5 psi, with original injectors and pump (Rawze thinks someone checked my pump, or could have, @ some point before I bought the truck, as it says steel on it in paint marker)
