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.
