NEW HOLLEY SNIPER EFI SELF-TUNING MASTER KIT,800 CFM,BLACK,4BBL,FUEL INJECTION CONVERSION

Great product just what I needed

Really performs nicely on my 351c (2v heads). Smooth and responsive, especially at low speed in traffic. Fuel pump is very loud. I may go to an in the tank set up to remove the noise there

Huge improvement over carburetor. Would give this 5 stars all day but the fuel pump is annoyingly loud. Will likely be making a change in that area.

I ordered the master kit. Took more than thirty days to finally almost finish build. The pump cracked when my mechanic attempted to attach fuel lines. Plastics PUMP. Holley sent me a better pump with no problems. Finally tried to start her up and the screen came up as no O2 censor connected. My mechanic contacted Holley. tried another O2 Censor and determined the problem was the ECU in the carb itself. Contacted Amazon and was told since it was past the 30 days, kit was not their problem. Had to return it to Holley after spending close to 100.00 dollars via UPS and was told by Holley it would take 4 weeks minimum to hear back from them. They will graciously pay for return shipping. You decide.

Took some time to install but it was well worth it effort

This unit is a beast. Complete woke up my old 350 sbc. Was not the hardest thing to install but you will need to set aside some time to make it all look super clean. The kit is exactly what it says “ complete “.

Very easy to set up. I put on my boat

Fairly easy to install worked great from the get go.

Looked awesome, powered up 1 time checking system then never again

I installed on a 1979 F250 everything done according to directions. Within the first month the auto on/off feature driving the fuel pump quit resulting in a no start. Fast forward 1000 miles and the O2 sensor failed. Replaced with a new O2 sensor direct from Holley and it lasted less than 500 miles. All told I have less than 2000 miles on the sniper and have been told they will not warranty the O2 sensor so the whole thing is coming off and going in the trash.

Thanks

This thing is awesome!! Works great its like night and day difference on my 78 chevy small block. With a real mild build. Just hit the key and go! Kit was package well and everything was there. Just install it right dont take bo short cuts
