that would be stage 3 tune. If you have 93 available I recommend running the 91 tune and filling with 93. It'll run much better and you'll get much fewer negative corrections. I'd recommend monitoring ignition corrections on all 4 cylinders. I usually watch knock detector. my last gauge is usually boost pressure cuz it's just fun to watch.
