@Mopar1972Man this is what my iat and fuel temp shows after driving a bit after n hour I got iat up to 156 and fuel temp remained around 120? Is iat temp to high? This is when it decides to give me partial engine load as you can see I'm almost 80% throttle. It says 3rd gear but it's in od and no green tc lockup light till you let off gas then it says 4th gear until you press gas again goes back to 3 and light goes off

Thanks @Mopar1973Man for your reply I’ll see what my numbers read today. Just curious I’m running stock trans with quad I see your quad shows you’re in 5th gear. But mine will only show an L for 1st gear and will only show up to 3rd when it’s in od is that normal? And I see your TC lockup is in green does it usually stay solid green or go away? Mine will pop up green then go away?

@Royal Squire I don’t think that’s the issue it was doing this before quadzilla was installed Never heard of this trick? I’m willing to try though I’m guessing pouring cold water over top of vp then crank? @Tractorman that’s what I’m thinking it’s going in and out of limp mode for some odd reason and not telling me. I’ll get a better scanner and see if I can get anything to come up

Thanks from the reply @Haggar ecm seems to be booting properly cel lights up when key is turned over and goes away I think that’s how we know it’s working? Im also leaning towards the vp considering the hard starts when hot. But also thinking it’s electrical or something else causing defuel. I’ll look over everything again and see if I can find something Thanks for your reply @dripley I would hope it’s just a failing map sensor! I’ll pull it and take a look at it see if it needs cleaning or replacement and see what happens. If the map sensor was on its way out would it be showing boost pressure? I’m getting 0-3 in town and 4-5 normal highway speeds if I accelerate it will go up with acceleration fine but when the dead pedal starts it will drop to 4psi and remain there until dead pedal stops. Also I’m not getting any smoke at all I used to get black smoke residue on rear fender but now even with chip turned up it’s all clean....

Hey guys looking for some answers on my 99 24 valve 3500 auto. It has bhaf/industrial injection vp44/and fass 150 with big hose lines and in tank sump all installed at same time about two years ago. Fuel pressure gauge is installed about a foot from ip with shrader valve cracked idk if it’s to close and giving an erratic reading but it will idle steady at about 14 then jump up to 18 while driving then all the way down to 10 then back up so basically it fluctuates up and down while driving between 18-10. Another thing that’s going on. sometimes it has a long start when hot sometimes not. And every day when cruising above 65 it will stop accelerating and only give me 30% throttle. boost drops to 4% apps shows to be working right with throttle response when This happens engine or rpms don’t shut down I can still run 60-70 just with only limited throttle and fuel pressure will stay at about 12-14 when it happens. Until it feels like kicking back in boost will jump up and engine will take off depending on where my throttle pos at time.showing no codes from autozone scanner. Recently did apps reset and didn’t work then installed new apps still nothing did reset on new apps and nothing. disconnected Grid heaters still nothing. Did alternator wire re route and still no change. Crank pos sensor went out. Was giving me code/ no crank/long cranks. Replaced with Cummins sensor. Code went away and still having the issues. Checked grounds and terminals/pcm connections all seem ok so idk what else to do really don’t wanna start throwing vp or new lift pump at it if it’s something electrical or ac noise! Pls help. Also grid heaters were throwing a code before I unhooked idk what was wrong with them but I just un plugged them. Right now I have exhaust manifold leak at back of manifold toward pass side and a little oil or residue on bottom of turbo I guess where it bolts up at bottom? Can still push 28 psi boost when it doesn’t lose throttle she runs like a top 80-90 idles and city drives fine till throttle drops on highway
