How did you D.I.Y. your computer tuning.

Oh boy, 14 year old threads.

Tuning is done by using HP Tuners or EFI Live. Those are the two options for changing the calibration information. Getting into engine tuning isn't for the faint of heart and will take lots of time to understand what it going on.
