[Product Review] Tuning School Home Study Course vs. Calibrated Success Instructional DVD
My next step was a home-study course: A Beginner’s Guide to Tuning GM Vehicles with HP Tuners Software, offered by the Tuning School of Odessa, Florida. Finally, I watched GM Beginner’s Tuning Guide, a DVD by Greg Banish’s “Calibrated Success” and sold by Summit Racing.
