I can't recommend EFI System Pro enough. Very knowledgeable about the products they sell, always happy to talk you through your options and point you in the right direction. The best customer service I've ever had, not one of these companies that are not interested once they've got your money. Easy and stress-free purchase from giving adv

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!

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!
