EFI System Pro had everything I needed for my EFI upgrade. Pricing was reasonable, shipping was prompt and Chris helped me with a wiring question during my install. The Tech Tips and discussions are also great!

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.

Everyone raving about customer service is telling the truth! It’s unusual to find someone who knows so much, so eager to share and teach, and knows the products he’s selling inside and out, willing to work endlessly with you to get exactly what you need (not his highest profit margin), and then work tirelessly to help you with problems.

They are the only ones got me a holley usb to can cable fast. Everyone else was backordered several months.
