I have a 1999 dodge ram 2500 with a 5.9 cummins and i am looking for some inexpensive ways to boost my horsepower. Any thoughts?

 

Do you have an upgraded lift pump or a fuel pressure gauge?

 

Intake and Exhaust is basic mods

 

Cheapest bang for your buck on a 24v is a tuner like an edge juice or quadzilla adrenaline. But the reason I asked about lift pump a fuel pressure guage is the stock lift pump is barely adequate on a stock truck. When adding power you need more fuel and if you're not getting at least 10psi of fuel to the injection pump at all times then you're setting yourself up for injection pump failure. I personally would recommend a good lift pump like a raptor, airdog, or fass and 1/2 inch fuel lines from tank to injection pump first. Also a fuel pressure gauge unless you get a tuner with a monitor because they can display your fuel pressure.

 

I'm going to disagree with spending your first money on intake and exhaust. Those won't make any measurable difference on a 24V Cummins. A tuner such as a Quadzilla Adrenaline (by far the best) or Edge Juice will make a HUGE difference.
But yeah, you definitely need a better lift pump first, and a fuel pressure gauge.

You also need a "built" auto trans first, the stock trans will die quickly under real power.
If you have a manual, a heavier-duty clutch is in order, as well as a bigger input shaft.
