depends. I sorta look at the 101 'cert' like a ase cert. Somoene who has been dealing with brakes for 10+ years goes and sits in the ase class, plays with there cell phone the entire class, walks out with a cert is now all of the sudden a brake bad ass because he has a ASE cert. Same goes for the efi 101 cert. If somoene walks into a shop with a dyno to get there car tuned, and sees that the operator/tuner has a efi cert, that might mean something to that person who drops there car off at a shop looking for a 400hp number. I know and you know that you dont need a cert to know anything, but to some people, it might mean something.
If I wasnt paying for it, i'd be all over it, unless someone is going to require me to go.
