Well...You can't turn up the fuel on a 24v as you can on a 12v, due to the VP44 being electroinc fuel injected, not mechanical. To "turn up the fuel" he will need to buy a "box" such as an Edge Comp, or BlueChip, or TST, or Quadzilla, something that Taps the pump. If you want smoke you can get a programmer, some people see quite a but out of them, but not everyone. However if he plans to get more fuel to the truck, he'll deffinitly want to buy some gauges! Fuel Pressure in these trucks is crucial!
yes, i would get gauge's first. I only had a superchip on 70hp and i pulled heavy loads w/o gauges and when i got the gauges i was really supprised that i didn;t melt something down before. But yes its all electronical, just make sure you get gauges or one that reads it for u like the edge juice.
