[QUOTE="a_moore, post: 1562200, member: 807"] Made the second adjustment a week ago and there was no noticable change. Started planning a modded a-pump or p-pump. The "boost fooler" clearly worked but the rack adjustments did nothing. Drove the truck to work this week, 400 mile trip. Going down highway at 80-85mph. Would barely hold that speed on hills. While pulling a long grade and holding the throttle against the spring stop...it took off like a rocket and rolled coal. I thought something was wrong. Boost went from 15 up to 30 right now. Did it a second time so i drove easy until almost to destination. Starting shoving down hard on pedal. It would jump into power just like flipping a chip. If i slam the throttle down it runs like crazy. Now i can do it on command. Smash pedal and it runs like i want. I assume the metering valve is sticking inside the pump, and letting it go into full fuel setting. I have been running a good bit of lucas fuel treatment and i assume that things are loosing up from sitting in the pump. I will not need any further fuel. Just to get this pump working correctly. Feels like the 7.3 with hybrids when the metering valve shifts. There is still some black left at 30psi. Hits 1150 egt now. Time to get the S472 on top and probably will need a gate. I see no reason for larger injectors or any pump work if my assumption is correct and it will loosen up and start working correctly. Has anyone experienced this? I could be wrong and at the edge of adjustment causing this. But it sure feels like the metering valve is just sticking to me. When you let off it immediatly slows down. I was scared it was going to run away the first few times. But i couldnt help but hold it there for a bit. [/QUOTE]
