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!

The Ordering process was so easy and non-painful. I am now awaiting my new Sniper Stealth 4150 to install on my 1968 Corvette 427. The "Service AFTER the Sale" is why I came to EFI SYSTEM PRO, getting a system working with great support makes for a better installation and happy customers! I strongly recommend EFI System Pro.
