Can a performance box cause damage to the VP44??

Well, even if you didn't pierce the wire, you installed a power enhancing device and the dealer knows of it. You are now at their mercy.
Performance boxes that connect to the VP44 *DO* tax the pump greater than stock operation does-- there can be no debate on that. Is it within the design limits of the pump? Perhaps. But Dodge doesn't warranty the full operating range of the VP-- just the part of it that is used in the factory programming.
So technically, ANY power mod, whether it's an ECM programmer, and Can-bus box, or a wire tap box can justifiably void your warranty.
The VP44 isn't quite the gem of performance and durability anyway. In fact, I was in a meeting today with a prominent guy at Cummins Fuel Systems and who mentioned the VP44 as the butt of a joke. I was the only one that got it.
So even under perfect conditions of super clean, cool, fuel with good lubricity, the VP would STILL be less than bulletproof.

Wouldn't it be great if a company designed an all new electronically controlled injection pump for are trucks that would bolt right in and work on the factory programming, but with with reliability and maybe a chance for higher preformance than a vp.

Of course a wire was pierced but I have never done anything more than some mild "Horsing around" on the street and there is probably not more than 20K miles on this pump.

My first pump failed on the first 5x5 pull. Even now I've only made a couple of level 5 pulls, just short blasts. Once camping season is done I'll probably flog it harder when I have the time to have the truck down waiting for a pump.

Mine did the same. Its generally accepted that the earlier pumps were weaker than the later models hence the 027 pumps with the 27 upgrades.
My second one ( brand new 027 pump) went about 7000kms then I put a wrecker special on and sold the truck to buy a 12v. Its been years since I played with them but at the time there was rumor that the aggressive timing of the comp was the issue more than with other options. It seemed that guys that ran a fueling only box stacked with a milder EZ for timing had less failures however there was no real definitive answer at the time.

Is that from the box I sold you, or your old edge box? If the former, that box is a curse!
