What is the point of adjusting the fuel pressure on a modern, computer controlled car?

get more flow from the injectors you have, rather then upgrading the injectors, and finer tuning of the system with boost.

I disagree. That's what I used to think until I actually did some flow vs. pressure experiments with the OEM Fiero 14.7 lb/hr injectors, and they appear to be a constant-flow-rate design. I measured very little difference in actual flow rate from 38 to 55 psi, which pretty much confirmed what my BLMs had been telling me as I varied fuel rail pressure.

Marvin is 100 % correctomundo ,, there is no need to ajust fuel pressure ,,any ajustment needed should be miniscule,, a good way to needlessly screw up is to start messing with fuel pressure ..
