I have a 1967 mustang that we put a Holley Sniper EFI kit on. The engine runs hot over 200 deg F. It also will just cut out on me driving down the road. This has happened 10 times over the summer and has restarted. Is the engine running too hot? Any one familiar with tuning a holley EFI ??

No direct experience. You might try posting in the DIY Tuner forum. This section doesn't get much traffic.

I have a Sniper on my 5.0 82 Capri. Having similar issues as well as others. New 86 tank and hardware for EFI picked up and will be installed this weekend. Are you running an external pump?
