What Our Customers Are Saying


“I couldn’t be happier with the results of the custom map supplied by Dav-Tec. The engine runs free and smooth even from a cold start-up and pulls progressively, purposely and smoothly throughout.”


“Many thanks to Dav-Tec for living up to his well-earned reputation. Following a recent camper conversation, insurance mandated the installation of an S5 Tracker. I did my research, and Dav-Tec kept coming up, so I opted for their Ghost II & MetaTrak S5 Deadlock Pro tracker combo.”
