can you turn the pump up on a powerstroke ? Please no bad name callin on me im new an just curious.

You can put a chip on it to get more fuel. They don't have a conventional pump like older diesels to turn up.

The mechanical fuel pump on the PSDs is a rwo-stage unit. The pressure is not adjustable other than at the fuel pressure regulator (and raising much above 70 psi isn't good for the rest of the injection system). The Hydraulically-actuated Electronically-controlled Unit Injectors (HEUI) basically act as their own high pressure pumps. Want more fuel, you need modified injectors and programming to match. Cheers!

No factory switches. The 'switch' that some refer to is likely a switch for a pcm chip (which controls electronic tuning for fuel, oil, etc) that they have on the dash. In that reference, yes, you can 'turn it up'...

This will not "turn up the pump" but will increase fuel pressure to the injectors..... Do a search on shimming the fuel regulator, also called the BB mod. Inexpensive to do and may make your truck run a bit smoother. As noted above for significant change you need to get a chip/programer and injectors, with supporting mods like a down pipe and gauges.
