[QUOTE="option2, post: 1490693, member: 29019"] Well I drove the truck over to the local Super Duty center the other morning, it was chilly out maybe 45*f and the truck ran almost flawless, no falling on it's face at tip in on the throttle, it was initially on a 75hp time so I figured what the hell and turned it up to a canned 300 tune, turned off TC and punched it at 45-50 and she broke the rear tires lose and slid sideways no problem, I had ONE very minor fluctuation in RP just as I was pulling into ford but nothing like it was before if that helps you guys, the lift pump is pushing constant 6psi under load, lowest we saw when loading up the engine was 4.8 psi which is within factory specs, I think if i swap in new filters on the FASS that will probably go up a little more even, also considering adding a sump to help with fuel and for future goals when I have dual pumps, waiting on all that until I buy a new 6.7 for a daily driver though [/QUOTE]
