Good stuff. I also recommend to those thirsty for more TuneBoy skoolin' go to their website and download both Tuneboy TunEdit and Tuneboy Diagnostics (they are free). The masks alone for the programs will answer most questions.

You can also get some of the maps from other models and load them into TunEdit and play with them some. For those that are new to the whole Air Fuel Ratio and what constitutes rich and lean conditions..
