Agreed. I did this with my first turbo charged Z and it was a nightmare. You only receive a basic tuning screen and unless you know exactly what you are looking at they can screw up your car and they will not be held responsible. You really need a real tuner to see what is happening and what he is feeling. It was hard to describe some of the things happening unless you do it every day not when you are road tuning it for the first time. Hell, when I put it back to stock and loading the stock tune it almost screwed up my car because we forgot to remove the larger injectors. Leave it to the experts when it comes to tuning. Trust me.
