    FRP

    Weak cp3, possible bad injectors, collapsing fuel lines, plugged fuel filter, sticking FPR is a few causes to that issue. Best bet is to fill out a signature about your truck what been done to it ect and use the search function. This has been discussed plenty lots of great answers on where to start.

    I'm willing to bet it's the Industrial Injection injectors.

    2008 lmm tuning questions

    What kind of shape are the injectors in and is there any boost leaks? What the calculated fuel rate at idle? Worn injectors and a minor boost leak can make these trucks seem like each tune isn't much different from each other. My balance rates were good the cfr was 6-8. I put new sticks in at...

    Running Hot

    When my OEM TC started slipping and I put a new built trans and tc in I had the trans cooler flushed but the trans would still run hot and I had to pull over and let the truck cool down on the hiway to get the trans Temps down. It took a second trans flush to get it right. Maybe the GM dealer...

    1 bad new injector

    Strange, there was no leaking past either copper washer on cylinder 4 and 6, so I swapped which hole each Injector was in with new washers Orings and bolts and all is good! Injector rattle is 90% gone and it has a buttery smooth idle again 😎

    1 bad new injector

    New washers were used and hold downs were torqued to 22lbs. Cylinders 2, 4, and 6 were extremely dirty on tear down, and I do recall not cleaning out the bolt hole for the injector hold downs. On those 3 cylinders as I did them first. Think it's worth pulling injector 4 and 6? I never thought...

    Am I in Trouble?

    They are charging you over 300% markup on the regulator. 200% markup on the alternator, and the fuel pressure sensor on these trucks rarely go bad. IMO you are getting bent over without lube, I sure hope it runs good after.

    1 bad new injector

    Hey guys, I put a set of brand new set (not reman) of injectors in my truck a week ago with 45 over LBZ nozzles on them and at first it ran really good. All balance rates are under +1- , except for cylinder #4 which has a balance rate of +1.8 and cylinder #6 which had a balance rate of -1.8...

    I use Banks CAI on mine with a DP 72mm. I'm using banks dry version of the filter and can go 50,000 miles without a problem. Banks filter is large. I'll post a pic of what my filter looks like after 10,000

    Anyone know the fuel pressure and mm3 while in high idle?

    My LMM with 40 overs elevates the idle to 1050rpm with 30-35mm3 calculated fuel rate and 6-6.3kpsi when cold. Egts are around 620F.

    Chasing a Ghost. Timing at idle.

    I have a log here if someone wouldn't mind taking a look at and see if anything sticks out. I'm curious why my maf looks like it dips around frame 300 at WOT.

    Chasing a Ghost. Timing at idle.

    Hey guys, I've been slowly fixing every issue on my truck trying to make it run like it used to. The problem I'm having is a persistent rough idle and sluggish throttle response with more than usual black smoke until the turbo lights. Even sometimes on my bigger tunes I get the odd pop or light...
