Like many others, EFI System Pro allowed me to dial a new Holley Sniper. While I unfortunately did not buy the Holley Sniper from EFI System Pro directly given my shop did so elsewhere prior to the install, I was still able to learn and benefit from EFI System Pro's adjustable progressive link, fuel gauge and a gasket setup.

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!
