Chris has forgotten more about EFI than most EFI technicians will ever know. His insights and guidance are spot on. When you ask him a question you KNOW you're getting the right answer. Today we passed a RIGOROUS emissions test with flying colors and my '79 CJ7 has never in its life ran as smoothly or with as much power as it does now.

Fast shipping, great tech support. Don’t buy your EFI anywhere else.

Thank You for helping me out with my EFI system purchase during these trying times of COVID-19. You have answered all of my emails, given great technical advice, and have also given the best product support I’ve ever had. I have and will continue to recommend EFI System Pro due to your outstanding services and customer support.

Customer service is top-notch. Chris was kind enough to answer his phone evenings and weekends to help me through some minor issues I was having. I highly recommend ordering your EFI system though him as opposed to other companies because it shows that he truly cares about the customer and knows what he's doing with these systems.
