They are the only ones got me a holley usb to can cable fast. Everyone else was backordered several months.

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

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 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
