I second the wide band O2 as a required tool.
Remember all the special tools and procedures for setup in check, measure, adjust manual were because they had no ability to see what the actual mixture was. They also assume everything is like new and stock. If you search there is more tunning you can do outside of the standard adjustments.
If you have changed anything on the engine, pistons, cams or exhaust you are outside of the standard calibration. I general tuning MFI (like a carburetor) is a series of compromises. You are limited by the fuel curve on the space cam and can only tweak it a little here or there. The baro cell can only adjust for so much. All of these variables and mile high plus elevation are what make a wide band O2 the best tool for tunning.
