Easy is a relative term, but the Rtek is pretty straight forward to work with. I would recommend working with an experienced tuner, preferably on a dyno where AFRs can be monitored while tuning to dial it in just right.
But getting started is simple - you get into the initial setup menu, check the boxes to match your car's FI setup (e.g., 550/550s, 550/720s, 720/720s). Assuming you're running the stock turbo at close-to-stock boost levels (say 10psi or less), and your fuel system is up to the task (good pump, correct fuel pressure and known/tested injectors) do nothing else with the Rtek and you're up & running with a safe map, and no more fuel cut headaches.
