All my issues seem to be RFI/EMI interference. Working on getting rid of it. One issue, i didn't put alternator back together real tight. Brought to shop and they got it straight. Didn't even charge me. Putting Ferrite clamps on many grounds and wrapping Holley harness wires with RFI tape. Then putting back the poly mesh after. If Holley knows their product has issues with RFI, why don't they shield the damn wire harness. Conclusion: to buy all the ignition parts that go with the Sniper.
