If someone brought to you their very poorly maintained Boxster, after striking them with a rolled up newspaper, would you likely use this treatment on it to cleanse the fuel system?

First, I never hit customers, even the ones I don't particularly care for, with rolled up newspapers or anything else; bad for the shop's image.
Use of this type of system would depend upon the issue involved; these cleaning systems are designed as a "last resort" type cleaning, but will not do anything for an injector with a mechanical issues (bent or pitted plunger or pintle, damaged seats, broken return springs, bad seals, etc.), or electrical problems (connectors, wiring, dying solenoid, etc.); it is designed to clean gummed up but otherwise fine injectors. Quite often with an underperforming injector, it is not dirt that is the problem; it is mechanical or electrical fault which requires replacing the unit. Because the materials of construction change with injector vintage, some injectors do not like to be exposed to the concentrated solvents used in these clean outs, plus the system does not clean just the suspected problems injector, so using the system because injector #3 seems dirty results in #3 being happy, but injectors in #1 and #4 now leaking because the solvent attacked the internal seals. This is why I suggest using these systems
sparingly and only when nothing else works, you could easily end up with with an unintended result.
