How to turn up or down injector pump on a 96 cummins I have a 96 dodge dually and for being "stock" it sure throws out some smoke, and im just wondering if anyone would have an idea on how to turn the injector pump up or down because im getting crap for fuel mileage (around 5-8mpg)

thats pretty bad. it could be boost related. check your intercooler hoses. even when my truck was around 400hp i would still get over 20mpg on the hwy. an easy way to tell if someone has been into your pump is look at the top of the afc housing. it is on the back of the p1700 injection pump. it shoud be under the back fuel lines coming off the pump. If the one of the screws does not have a "head"(any way to take it out) it has not been modified yet.

If it's throwing smoke with stock power, then it sounds like you have a boost leak. The break-away head screw was done from the factory. And if the paint on it doesn't look like it was disturbed or broken, then it should be stock.

at least 14 m.p.g. even with a lead foot. maybe the timing has slipped

Thanks lil dog website helped, i check all the intercooler hoses and they seem fine from what i can see, any ways i noticed the break-away head screw is missing some paint, and that means it has been messed with correct, how would i set it back or whatever............Another question, can stock 12v dually burn tires off with loaded car trailer.......?
Feb 6, 2018 Free horsepower has a nice ring to it, doesn’t it? In this day and age, it’s almost a foreign concept to think that you can add power to any vehicle without first opening up your wallet. However, there was a time when turning wrenches led to solid performance gains. For the ultimate example of low-buck power-adding, look no further than the ’94-’98 3/4- and 1-ton Dodge Rams equipped with the 5.9L Cummins. Thanks to being graced with the Bosch P7100 injection pump (aka the P-pump), 100 hp or more can be unleashed once a few key areas of the mechanical pump are modified. All that’s required is a little bit of your time and a few simple handtools. If you’re still using one of these old Dodge workhorses around the farm or are thinking of picking one up because it’s cheap and will last forever, don’t be surprised when it struggles to keep up with traffic. These mild-mannered mid-’90s Rams only sent 135-150 hp to the pavement in stock trim, which is all the more reason to break out the wrenches and turn up the P7100. With the fueling tweaks listed here, you can darn-near double the factory horsepower rating while tripling torque output—and it won’t cost you a thing! And for those of you who don’t plan on stopping with the freebies, we’ve also included a few subsequent steps you can take in your pursuit of additional power. *Note: all performance gains mentioned in this article assume that the truck you’re starting with is mechanically sound (i.e., a P7100 in good overall health, a strong lift pump, and injectors with adequate pop-off pressure).
