This is how I've been doing it, one step at a time. Considering my 106k miles, injectors being dirty makes a lot of sense. Bought some in tank cleaner and studying up on injectors. Looks straight forward, injectors are spendy though to start slinging parts at it when they likely just need cleaned.
Gadgets needed are less than an hour of shop rate, may give it a try. An injector cycler, cleaner adapters, cleaner and maybe a small ultrasonic bath. Saw one video where a guy had saved old injectors he had to replace and couldn't get to clean with the spray through method. Cycled the injectors in the US bath in the cleaners and had them cleared in minutes. Was impressive.
But getting a log sure would be nice to get in front of the tuner types. I'm sure the signal is there. Little more work to do personally before I pull the shop trigger. Just watched a video on the GDI system, if I have to go in there, definitely going to a shop.
