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!

Super informative, fast shipping, and so far a 5/5 experience! Strongly recommend.

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

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.
