^^^ exactly, 7.3s (and 6.0s) are a bit of a different animal with the HEUI system, shops that might be able to do wondrous things with CR engines (Dmax, 6.4s, 6.7s and 03+ Cummins engines) might not have a clue what do to with a HEUI.

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.

 

ok well that helped alot! thanks fro your help fellas!

 

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.
