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.

I decided to buy from EFI System Pro hoping for better customer service than, say, Summit or wherever else. Boy, they didn't disappoint. Chris Myer is a tremendous resource for info and questions. Emails are answered immediately. I highly recommend them to anyone deciding to go EFI. They are the only way to go in my mind. Thanks, Chris!

Very Quick Shipping & Help Guides Have Been Invaluable For Setting Up My Holley Sniper. Great Company!

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!
