Truck has a ~650/2250 tune and I’m sure the fuel harness on top of that did NOT do me any favors long term. It messed with my fuel actuators which I had to replace. Stupid on my part, never again.

You are right, I do have to point it out so that others can learn from, and stay well away form this type of backwards and abusive thinking...

That could totally explain the damage to the injector can bearings. not only do those stupid fuel fooling gimmik devices fool the ecm into thinking the fuel pressure is lower then it actually is, but it screws up the amount of fuel goi9ng into BOTH FUEL CHAMBER AND THE INJECTION TIMING CHAMBERS -- screwing up not only fuelling, fuel-air-mix, but also injection timing too. -- ALSO--- it very easily can over-fill/over-load the injection timing chambers of the injectors right along side over-filling/over-loading the metering chambers,... LEADING DIRECTLY TO EXCESSIVE CAM AND CAM BEARING OVERLOADING and stress. this is because of the excess injector height due to the the over-filled chambers. -- I.E.> THOSE GARBAGE-CAN DEVICES DO NOTHING BUT CAUSE DAMAGE, EXCESS DETONATION IN THE TOP END AND CHAMBERS, AND ABUSE, FLAT OUT!!!.

THROW THE F$^$ER IN THE TRASH CAN... immediately! -- AND GET THAT ABUSIVE PROGRAMMING OUT OF THAT DAMN ENGINE!!!

-- Now you know what the full story is,.. now you know that you cannot just abuse these engines with bulls@4it!... now you are paying for these mistakes. -- Like I said, the failure was not a normal process of wear.


-- ALSO-- with 2200+ft-lbs torque in that engine -- YOU ARE ABSOLUTELY ABUSING IT!!!! --- IT IS ADDED TORQUE THAT RUINS THE ISX, NOT SO MUCH HP!!!. - It is a matter of time, and you will be next crying that it dropped a liner!


YOU WANT THE TRUCK TO PULL BETTER--- FIX THE REAR AXLE RATIOS AND STOP ABUSING THE MOST EXPENSIVE COMPONENT IN THE DRIVE-LINE (the engine)!!!!

-- hopefully, you are starting to learn that the term "super-trucker" == "stupid-trucker!" and all the gimmicks and garbage on the internet and advertised that goes along with that type of s$ittyy thinking that plagues our industry. Get those kinds of thoughts out of your head and use it for more productive things like re-spec the rear axles or something that actually makes sense instead of resorting to abuse and then wondering why things fail.

Hours of run time are around 21,000. Been a local haul truck it’s whole life

And this isn’t an LOL type of situation but your brutal honesty on these topics always makes me laugh a little because it’s all true.

That harness was the worst idea I could’ve had I regret it everyday knowing what it did. 6 months of it and then I yanked it out. Hopefully others will learn from my experience with crap like that.

I had the tune done 4 years ago from someone here that’s done quite a few. Supposedly it’s around 650hp/ 2100-2200tq I believe? Truck has a 8519 cpl, heavy drive line and 2250 clutch. 100k gross on 5 axles isn’t easy on a truck so I tried to set it up for what we do

I suppose a 500/1850 may have done me better longevity wise. Also of course no stupid over fueling harness
