Looked into these, it needs to have pea as the major ingredient and this is nothing better than a bunch of clear liquid.

For those looking for the Chevron Techron PEA version, just search for "Chevron Techron Complete Fuel System Cleaner" on here and you'll see a few deals at Napa, O'Reilly, AutoZone, and Checker. Check locally if they're still active, and if so congrats. 👍

Direct injection is an abomination. With port injection the gasoline keeps your intake valves clean. With DI you get both injectors and valves all coked up... for very little benefit.

Absolutely if you indeed need the system cleaned and you use a 'complete' system cleaner with PEA. Like another commenter said, if it doesn't have PEA it is literally useless.
