ok thanks for the feedback, but could you name some mods? i want to get 100hp injectors, and a 17* HPOP, can someone tell me if the new HPOP is nesessary? also what upgrades vwould i need to support the injectors? i know these are stupids questions... but this is my first diesel. thanks for your help!
Stay away from (xx horsepower) injectors. You will have no way of knowing what you are getting and therefore, you won't be able to tune for them (and they won't tell you). You and your tuner will want to know the capacity and nozzle size. Capacity is measured in CC's and nozzle size wil be % over stock. See a reputable injector site like Rosewood. His site will explain what you want to know.
If your doing injectors on a OBS 7.3 you should upgrade the fuel system to external regulated return set up so they are not starved for fuel. If money is short, I wait and save up so you can bring the power adders and supporting mods (fuel system, HPX, trans, Head studs (depending on boost)) on at the same time...other wise your spending a lot of money and not getting much.
When you get your DP tuner, talk to Jody and he should be able to help you map out a plan for mods and power.

First get gauges. Run the truck for a week stock to make sure all numbers are where they should be. Custom tunes to get more performance stage one injectors and a boost cooler and even a bigger turbo. But not to much bigger bs diesel makes a turbo called thrusters 2 that's how I would build a mild modes truck.
