      Holley Sniper efi

      So I sent back the FAST and bought the Sniper mostly because the reviews were terrible and also tech support and customer service seems to be awful. Everybody says it way better with Holley so we'll see.
      So anybody ride using the Sniper on a track car?

      I just installed a Holley sniper on my car. Swapped out a 750 Vacuum secondary Quick Fuel carburetor to this. I installed new fuel lines for better flow.

      It is rated at 850 CFM and supposed to support 650HP. It was easy to install took about 5 hours from start to finish. I bought the "master kit" came with fuel pump filters and hose in addition to the throttle body coolant temp sensor and Oxygen sensor.

      Out of the box there were quite a few problems. The display/controller had the wrong software loaded in it. Was not the Holley Sniper software it was for a different system. The SD memory card was bad, could not read or write to it. I contacted Holley Tech support and they sent me another display unit with software loaded and it would not work either. Another bad memory card and Now it would not recognize the ECU in the throttle body.

      Holley Tech support told me I would have to send it to them for repair. I boxed it up and took it back to Summit and they swapped it out for new one.

      This one worked better but still could not read or write to the memory card. So it would not let me upload the preliminary tune. I had a SD memory card so I downloaded the files and moved them around until the unit would read them. Not sure exactly what the problem was but there seems to have been several. I have since seen a couple other people report the same problems on the holley forum.

      With that said I am pretty happy with it now that I have it up and running. It learns really quick and has a really snappy throttle response. I am having a serious problem getting the engine to start when it is over 180 degrees. I am working on the tune to resolve this once that sorted I think I will be happy with my purchase so I would recommend the unit. The tuning software is really powerful and you can even control timing, nitrous and it will work with boosted engines.

      One question I have that is pretty dumb probably. But the fuel pump it comes with. I'm not sure about my current fuel pump. I believe it's in my tank and works with my carb. Will the pump provided work without removing my current one? Or do I need a new tank?

      Pontiac 400 with msd and Holley 650 carb.....thanks fellas!

      The best solution for an EFI fuel pump is an "in-tank" pump. You can use the master kit and mount the pump on the frame rail, but even Holley suggests an in-tank pump.

      You may already have an EFI compatible fuel pump in your tank, with a bypass regulator which would allow it to work with low pressure that a carb needs. Try to find out what kind of pump you have now. Once you know what kind of pump that is, you can narrow down your options.

      Yep, I've used that too. Holley recently took over admin duties on the FB page. Some of the replies come from actual Holley employees. Just have to figure out who to listen to.

      Me too. Now that Sniper has been out for awhile, who has real-world experience with installing and running both of them? I have 2 Pontiacs ready for EFI. On both I want the factory air cleaners to fit. Not worried about supertuning, just want reliable drivers.

      If your using the Sniper's, highly recommend using the USB dongle, 558-443. Lets you use your laptop instead of the handheld. Software is much better and has access to more parameters.
