hmm depends i have far more respect for tuners in other fields like race bikes (ten times our engine technology), jet, boats and southern 80 boats and especially race aircraft...... put simply if you tune a plane wrong it ends in death.....
its all about what vehicle and for what application..... carb, injection, land, sea, air etc....
Drag tuning (EFI) is by far one of the simplest facets of the tuning game.
