I did not buy my holley sniper from EFI Pro Systems. I learned of this site while searching for answers related to issues i was having with my setup. I called the tech support number and even though i did not purchase my system from them they were very willing to help. I had actually called to inquire as to which upgrade card i needed for

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.

Fast shipping, great tech support. Don’t buy your EFI anywhere else.

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!
