My VP44 died a couple of weeks ago. The truck has 92,000 miles and it's the second VP44 to die. The first was covered by warranty. This one is on me so I'm going to use a different approach. A reman VP44 is on the way from US diesel and I'm going to order the vulcan big line kit and relocate the lift pump. I also have an AFE stage 1 to install. Since I'm doing upgrades, The little woman said I could buy some injectors and I've decided on the Jammer series from Edge. I'm thinking stage II or stage III. I pull a 5ver at 7,000 pounds and once or twice a year I tow two 4 wheelers on a trailer for an additional 4,000 pounds at high elevations. Do you think the stage IIIs are too much? What will be the drawbacks? I appreciate any input.
