Beware Of Power Puck

[tmh1955]

After using a Diablo Sport Power puck for 8 months, my injector pump failed yesterday at 47000 miles. Of course I cannot prove it was the Puck, but I have my suspicions. Luckily Cummins warranty is covering it since I removed the puck prior to bringing the truck in.



It sure runs good with the puck, but:



Use the Puck at your own risk.

I was in the same boat in my old 01, But at least the dealer put it in and they didnt care, but when I put the comp in they couldnt do a whole lot because of that little piece of insulation on the wire that got mysteriously damaged.

Sorry to hear that. Are you running a boost fooler and elbow with yours? I'm running a version of the powerpuck for the last 70,000 miles and I haven't had a problem with it. I don't have a boost fooler or elbow though.

 

[Bob Wagner]

were you running a fuel pressure guage? if so, what were your pressures?

 

[tmh1955]

Power Puck

No fuel guage, so I have no idea

I know after I installed my comp and mach2's my stock clutch is nearing failure.



Beware of comp box and mach2s!

Now I'm not trying to be controversial but it doesn't appear to me that you did not use it at your own risk since someone else is paying for it! You need to check your fuel pressure and make sure you have some. I honestly do not believe that the puck caused the failure, it may have caused it to go sooner from being worked harder but it was bound to fail. The Edge Comp is probably one of the toughest boxes for a pump and mines been on since 42,300 miles and I now have 102,915 miles, the box gets set to 5x5 almost everyday and is usually left on 2x3. My pump hasn't died, but then again I monitor my fuel pressure going to the pump. Could just be you had a bad pump

I've had a Puck on my truck for close to 100,000 miles with no adverse affect. The lift pump was replaced under warranty at 98,000,but I doubt it had anything to do with the Puck though. I now have 126,000 plus on the truck and still showing 15lbs of pressure at idle.

There have been injector pump failures on bone stock trucks. If the lift pump goes south on ya, and you don't know it, it could have been the cause of your failure.



I don't believe it's fair to blame a product when you don't know for sure that it caused the failure.

 

[MCummings]

The injection pump is a very capable, but feeble pump.



Kinda like a female with PMS,, when it wants to crap out on you, it will.



I've replaced both modified trucks' pumps, and stock truck pumps. They all seem to fail nearly the same way.

Hard Start when hot, and/or dead pedal.



I've gone through about 4 or 5 pumps on my truck in the last 2 years (when it was running, 3 if you count the time it was parked )

I agree with others. Any time you modify your truck with a fueling box, you need to remember this, "I am my own warranty station. " If you can't afford to pay, then you better not play...

 

[tmh1955]

Hey guys, it was just a friendly warning. Jeez! Thanks for the flames guys, I'll never do this again.

 

[RustyJC]

I'll never do this again.

With all respect, if you're going to run a BOMBed truck with no gauges, don't even know what your fuel supply pressure to the VP-44 is and then blame a box for the VP-44 pump failure, that would probably be a pretty good idea.

I think we need to ban the term "I am my own warranty station". It's starting to get pretty old. I agree that this is a concept that should be taken into account once it was investigated what may of caused the failure; but to automatically assume that the failure was due to a mod rather than a manufacturing flaw of the part is no better than what the dealers do. I'm getting sick of hearing it. And on the other side of the equation, to assume it was a flaw and have it replaced under warranty rather than stepping up to the plate and admitting it might actually be the mod is also lame.



I for one will always do what I can to determine what the failure is and in good conscience will make a decision. I also will remove my mods when I bring it in for service just because many dealers also jump to this conclusion. But I in good conscience know that a failure isn't to blame for the warrantied part. For example, I tried to get the dealer to replace my lift pump when it failed but I removed my Edge EZ before I brought it in. I know that the EZ didn't cause the failure. AFter all, the same amount of fuel is pumped through the lift pump regardless of if you have a EZ or not (this is 2nd gen trucks... I don't know about 3rd gen). The only difference is more fuel may be used in the engine rather than being directed back to the fuel tank... . Just be honest with yourself... . but stop using the "i'm my own warranty station" cop out... it's getting really old.

My statement about, "I am my own warranty station" is not a cop out. If you alter the fuel delivery in any way, you're working outside the parameters of what DC has designed and they can and will void your warranty. Do you think it is morally and ethically right to claim warranty work on a VP44 when they've been using an EZ box? If you're really concerned about warranty, then you should keep it stock until you reach 100K miles. I've got plenty of BOMBS on my truck and I'm prepared to pay to repair any failed parts.

THe powerpuck won't kill your injection pump.



It does not exceed the limitations set by BOSCH. The VP44 can pump out 330HP in "Emergency" services (e. g. Ambulance)



If there is a place you don't want stuff failing, it would be an ambulance.



A Power Edge COMP, TST COMP box, Blue Chip Box (redline and FMS), and any other box that pierces the injection pump wire overides any computer control that is programmed inside the VP44.



At that point, Injection pump failure could be because of overheating of the solenoid, or just from a bad pump.



If your pump doesn't fail within ~30 minutes of putting on a Wire Piercing box, then it most likely will not fail from a direct result of the fueling box.



TST has tested the Solenoid inside the VP44, and found no more power after ~69% Duty Cycle (That is not an exact number, but close).



If I can hijack this thread,,

Buyer Beware of the new FMS Redline box from Blue Chip. You can control duty cycle of the solenoid to 100%. This will lead to failure of the VP44. Many people will take this risk while in competition, and many wil pay the price to win...

(The Redline box does have an adjustment for the Duty cycle of the solenoid, so it does not have to operate at 100%)

The powerpuck won't kill your injection pump.

Ditto. Thanks for looking out for us though.

My Two Cents...

First, I believe in being honest all of the time. I take my trucks in for DC service with all mods on. My DC dealer and I have a great and honest relationship. They know I'm a regular customer and they want to keep me.



Second, I am my own warranty station does not mean necesarrily everything is automatically the fault of a mod, it means be prepared to pay for a related failure. For example, my injection pump was failing on my 3500. I was prepared to pay as I have TST PM3 Adjustable and DDIIs on it. And I told my dealer about the injectors. They replaced the pump under warranty, but I was willing to pay for it because I know my mods affect the fuel delivery system.



I worked many years in government communictions equipment and software contracting. I would have government employees alter the equipment or programs outside OEM recommendations or tamper to get better results. Then when a problem would occur, they wanted warranty help. The point is, when we alter our vehicles outside their configured or designed parameters, we are responsible for the outcome.



Finally, I'm not flaming or critizing anyone. I'm just offering my opinions, which is the design of this forum.

Don't take it personally. All they are saying is... what really could/may have caused the failure. If you didn't have a fuel pressure guage, it could have been due to low fuel pressure. We all know that the VP could have failed single handedly. Is it due to the puck? After reading many many posts on why the VP fails, I don't believe that is what caused the failure. That is what everyone is trying to say.



Generally people on this forum get defensive very quickly when you blame a product for the failure of a part. From a Clutch, to a Auto Transmission, to a cup smoothie.
