Work great
I decided to try this Sniper System to help eliminate tuning a carb on new engine I installed in my Chevelle. I recommend you watch the install video a couple of times The manual is a on line PDF file and try to understand it all before installing. After reading and watching it is a easy operation. The wires are easy enough and I used a in tank fuel pump kit for my instal I chose that over drilling a hole in fuel tank for a fuel return line. Now I just drive and watch it tune itself. So far so good!!!!

Works great
System is great and easy to install the only problem is the kit is not complete it doesn’t come with the two into one fuel line you have to order it separate part # Holley 34-42 and it $124.00 which is no big deal but it says this is a master kit which should include everything. It cost me about two days wait time but I’m very pleased with it
