Everyone raving about customer service is telling the truth! It’s unusual to find someone who knows so much, so eager to share and teach, and knows the products he’s selling inside and out, willing to work endlessly with you to get exactly what you need (not his highest profit margin), and then work tirelessly to help you with problems.

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

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.
