I have been seeing this very randomly and rarely in my logs during WOT pulls. The trigger indicator boxes go red above 5500 rpm and stay read until rpms drop more off throttle or I shift and pull again. It's sort of rare and very intermittently.
I have new bellhousing sensors but they are eBay ones on the cheaper end. As far as I know the machinist DID NOT balance the new rods lol. He says "oh it's so minute it doesn't matter and also carbon buildup throws it off eventually anyway" and this is the guy who's crew destroyed my oil check valve and left me no pressure reading after the engine refresh!
Anyone think it's the poopy sensors? Thanks for reading

Ign noise can cause this. Make sure your shielding on the trigger wires is good and away from the plug wires. Also run resistor plugs if you are not. Most factory are but the NGK 8 and 9 heat range plugs are not.

I found some causes of my trigger errors. My DIY PnP adapter. The VR signal wire and cylinder 1 ignition trigger had a bad solder. Fixed.
However, still have a secondary trigger error at times when dropping below 600rpm or so.
