Do you or know of anyone that runs this pump? Do you like it or don't like it? Pro's, cons's ideas suggestions? Thanks

 

What HP are you looking to get?

 

I have one... My only issues are when I did the hr pump my vp codes never cleared, are only picked up by a scanner but they are there... and the wierd idle the hr pump has is, interesting. Customer service at IIS is A+, if you call them you talk to a real cummins mechanic, not some guy at a desk.

What do you have done to your truck so far?

 

a buddy of mine has one and doesnt like the hard starts in the cold and the wierd idle it has. when i drove it if i let off a little it had a really odd stutter till you gave it more gas or fully let off. other than that it screams

 

a lot of ppl i have seen on here seem to think the Standard Output pump is the better option... maybe u have that and are looking for more... thats just kinda the concensus i have found..

 

Thanks guys for the info!! Right he truck has a edge juice with attitude, stage 2 injectors, air box,fass and im thinkin that's it.and I really don't have a power range with this truck other then get up and go. But I am lookin for fuel milage tho.

Whenever the stock pump went out, a mechanic ordered a pump (surpose to be a hott rod pump) the truck hasn't been the same since. And im holding this will fix the problem

 

What do you mean "the truck hasn't been the same since"

I wouldn't go buying a new vp if you don't know what's going on with it... whats your fuel pressure from idle to wot? codes? symptoms?

 

One of the biggest diff. Is fuel milage and power. And such as fuel pressure, it jumps from 14 to 15psi all around.

 

Are you using a Mechanical or Electrical Fuel Pressure Gauge?

 

Go with a standard Output VP44 and upgrade your injectors to be bigger if you want more power. SO vp44 will support 650HP and is generally more reliable.
