I first contacted Dave Ehrlich of Autotrend EFI in 2014 for help in replacing the fuel injection system in my Shelby 427 Cobra replica. From the beginning, Dave proved to be a valuable source of automotive knowledge, practical knowhow and good advice. Over the years he has consistently met or exceeded my expectations in guiding me through the process of choosing, buying, installing and tuning a new EFI system for my Cobra. In addition to his tremendous technical knowledge, Dave is patient and very skilled at explaining anything and everything I asked about--and I asked MANY things over the 6-year period I've worked with him. Dave Ehrlich is that all-too-rare combination of vast technical knowledge, ability to teach and explain and highest ethical practice. Dave guided me in installing and then tuning a new Holley Dominator EFI system on my Ford 427 Sideoiler engine, all by email, text and cell phone. It worked out great. My Cobra runs like a dream.
