I took EFI 101 a few years ago, Ben Strader was the teacher, he writes those EFI tuning books that you see in Lordco /Mopac. It was in Seattle though. Well worth it if you plan on running a Standalone EMS in your own car. He really covers all the bases and gives you the theory behind the tuning.....lots of math. I would reccomend it for sure.
Ya i have a standalone in my car and been really wanting to learn tuning for a while, just in the middle of my apperenticeship at the moment, hopefully ill have some extra cash in the summer to attend that.
