Hi mate, I am exactly on the same page as your buddy and I am trying to learn by myself as my previous tuner closed their shop and it looks like they just didn't care about the last tunes they did. I'm actually starting to learn and seeing this and you have the same setup as me makes me pursue that I really need to study more on this. My car feels like it's gonna detonate lol! And lots of part throttle delayssss!!!
