The thing is that larger aftermarket fuel injectors are going to require slightly different programming than your stockers. For example, you could go to "Stage 1 injectors" (160 cc injectors with factory size nozzles) and using tuning for 90cc injectors would give you NOTHING in terms of performance. Stage 2s would be pretty radical (read: close to undriveable and not real healthy for the crank and rods) at low RPM using factory-injector tuning without correcting for the larger nozzles.
It all depends on what you plan on doing with the truck and its' modifications down the road. The fueling will be a little heavier at the bottom (while there's enough fuel left to be injected) with the higher HP tunes but for the most part, you'd just be throwing money away.
Hope this helps.
