Yeah, its kind of a big deal. That's why Cobb certified means that Cobb gives them a stamp of approval to tune for AP. They as of late send out a representative or two out to the shop and show make sure they pass their guidelines for tuning. My local shop just got GTR and Mazda certified and Cobb sent out two representatives from their main office to give my tuner a little education on the GTR and mazda programs. Now, he is licensed as a tuner for EVOs, STIs, GTR, and Mazdas. He also does OS tunes...so, my tuner can do various kinds of tuning.
