I went to the EFI 101 classes this weekend and I have to say that is was the best money that i have ever spent on my car. Ben Strader made the whole tunign process look really easy. Ben spent time not just telling you what to do but how to think for yourself. He taught things in a manner that I had never thought about before so, with this new way of thinking, the “black magic” of tuning was gone. He also pointed out that many of the tuners that you and I take our cars to don’t know what they are doing, they just had the money to buy a dyno. From the stories in the room and my experence with tuners I feel like the me and my classmates have a better understanding of the correct way to tune better than many of our tuners. Ben also never acted like he was a tuning God, he comes across as a guy who just wants to be the best he can. I would recommend this class to anyone who is messing around with EFI, SEM, and high horse power NA and turbo. The class was about $500.00, but well worth it and more.
