Chris Macellaro has started a new EFI tuning class series called EFI Tuning Technologies to teach advanced EFI tuning and diagnostics. In addition to tuning, this class covers such things as how to troubleshoot EFI with an oscilloscope, sensor calibration, how to filter noise out of your EFI's signals, and more. We're hosting a class from Feb. 27 to Feb 28th at our shop in Suwanee, GA. There are other classes in January at Import Car Center in Grapevine, TX and EFI Logitics in Bethel, CT. The cost is $495 for this class, and you can sign up here.
