2002 cummins best programmer

Posted

I have a 2002 2500 I have a superchip programmer now. But I want more power. I bought the truck used it has a fuel pressure gauge which shows 30 psi all the time. My question is can I run a quadzilla without burning up my pump.

    Fuel pressure is one of the keys for the VP trucks. Keeps the pump happy. Then if you shove a lot of power out of the engine, the drive train better be able to handle it.

    Yes you can run the Quadzilla without damaging your pump. I ran Edge Comp for ten years and now the Quadzilla now. My last pump ran till 243k miles.   4 ways to kill a VP44.. 1. Low fue

Guessing the gauge is kaput verify what fuel presdure with a second gauge.

 

Can't answer the question until we know if the first gauge is right, 30 psi high for a VP setup

    4 ways to kill a VP44..

    1. Low fuel pressure.

    2. Poor filtration.

    3. Excessive AC noise.

    4. Poor publicity.

    No, but also unneeded if the pump is good.

    That’s what my Fass is currently putting out.

    The funny part is if you talk to a VP44 rebuilder they claim the wiretap put undue strain on the pump. Which to this day no one could ever prove it just used as a way to prevent wiretapping before warranty. With all the HP junkies out there and all the tapped tuners on the market there has never been a pump failure due to wiretapping. Maybe from shorting wires out... But never from a tuner aspect that I've heard off. You now got vendors like DAP that sell pumps at an increased price with wiretap warranties.

     

    Thousands of tapped VP44 can't be wrong.

     

    Like in the past a lot of pump vendors use to use the "blown diaphragm" claim to why a pump warranty was voided. Now since my article on the truth that it a "steel plate" seems that cliche' finally died with the truth.

    Meh I could see how wiretap could burn up a fueling solenoid due to extra heat build up in the solenoid wiring.   

     

    I dont think it is a major reason for failure though.  timing piston failure is a MUCH bigger issue.  10:1 if I look through the posts
