RB sounds like it's hitting limiter over 6k rpm

This just started a few days ago and I have been racking my brain to try and figure it out. RB20 with AEM S2, Stock coils, Supra TT fuel pump rewired. It seems like after 6k it sounds like it's hitting the rev limiter but it will keep pulling past 6k rpm. I pulled the plugs and they look clean, A/F is a solid 11.0, regaped the plugs from .25 to .20 and still doing it. I want to say coils? since they are probably old as fuk. Last time I had a coil go bad it was would cut out at idle and pick up when it was reved?

Nm switched out the ignitor for a spare one I had and it seems to have cleared up. I am going to convert over to the LS2 truck coils anyway.
