My only real experience EFI tuning is from going to the EFI101 course. But from this and my experience setting up my EFI system, I believe the tuning is a breeze. Setting up the EFI is another story. I wouldn't mess with any auto-tune software. Just schedule a few hours on a dyno with someone familar with you're ECU and you're set except for maybe another check on the dyno when the weather has change significantly. You must tune it on a dyno or you're wasting your time, money, and maybe your engine.
