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

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.
