If your on Tapatalk here's my signature:
2000 F-350 SCLB 7.3 4X4 ZF6 :fordoval:
Turbonetics T-4 w/ S468 FMW, Swamp's 300/200%, Swamps Gen3, Irate Comp Fuel, Irate 3" Plenums, ARP Headstuds, Comp 910's, Smith Bros Pushrods, Hydra with Tuning from Gear-Head and Swamps.
My truck falls flat on its face when I accelerate hard and i'm looking for any input or ideas of things to check if anyone has had similar issues or has any clue on whats going on. So if I hold it past 3/4 throttle it will spool and start to pull for about 3 seconds and then boost will drop from around 50lbs down to about 4lbs and nothing will change until I lift. As soon as boost drops it smokes like a freight train and goes nowhere. If I keep it under 3/4ish throttle and under 40lbs of boost it feels great. Fuel pressure never drops below 65psi, ICP never drops, and my IPR DC is at 36% at 3300 psi. It has always done this but I figured ICP was dropping because I had a stock HPOP at the time with everything else in my signature, but I just installed a Gen3 the other day and it pulls a bit harder right before it falls but it still does the same thing. I just data logged it today and below is a captured pull, the first picture is before it falls off and the second is after. One noticeable thing is peak boost on my mechanical gauge is 50lbs, and the most my MAP sensor ever sees in the pull is 39, so roughly 24.3lbs. The other thing I notice that's out of the ordinary is my injector pulse width is 5.18ms at one point, isn't that high? thanks for any input.
