    If you have a lot more than 5 volts at your MAP & TPS sensors (unless the Sniper EFI somehow uses +12V MAP & TPS sensors), contact or email Holley Tech Service (LINK).

    Tech Service will replace it, but I should send that back first. Not OK I have trusted Holley, but they don't trust me. Normally that was funny, it was the first unit and we share a birthday.

    UPDATE: I think I located the problem. The MSD HVC coil will not work with EFI. After we changed it, and changed EVERYTHING, we located the coil as the problem. Standard coil installed, and all was fine. What software I need to read Sniper datalog file?
