Message: [QUOTE="FaSSt9602, post: 850235, member: 1872"] How new is this "new" unit? I had a "new" updated pump sent to me a year ago, and it isn't fairing much better than my first pump....pressure drops off with stock injectors and pressure fluctuates dramatically with temps and lenth of drive. In the summer (110+ out) I have to baby it under half throttle just to keep it above 45psi. Winter isn't quite as bad, but still drop below 42psi WOT. :fustrate: I have my RR set to 48psi just so it doesn't drop like a rock like it will if I try to keep it at 60+psi. [/QUOTE]
