You can start raising the values at the top until the fuel pressure is down where you want it with the lift pump turned up.

Thanx Josh , Do you mean the top 3 or 4 ? And what should i change them too? im afraid to screww something up...im still new to this if you give me some #'s i can change it ,im just not sure how to do the math and figure it out for myself,Rob says 5% at a time is this true?And also would this be right to do example change 1550 to (1627)???:confused:
