Yeah, the EFI provides lots of adjustability, but I'm not sure changing jets might not be easier sometimes. I tend to like to tweak graphs & tables, and before long it's all messed up and I have to backtrack...

Every time you make a major change to the tuning you (should) save the file with a new file name. if you find you went the wrong dirrection you just switch back to the prior configuration. that whole senerio took about 5 mouse clicks and 30 seconds. try matching that time by changing jets and fuel pump cams.

Yep, that's indeed the way to go. I think I'm up to file #13, but #7 has alpha suffix's that add ten or twelve in the middle. I often do a "save as" with a "Test" added to the number, and then blow it away if it doesn't pan out. Last night I was on my way to a local cruise, and I realized that the re-configuring of my spark map was not working right so I grabbed the handheld calibrator while stopped at a light, dialed in "Global Spark Modifiers" and was able to take out six degrees across the board temporarily, then go back to the previous spark map when I got home. It's pretty slick, especially if you like to tinker...
