Thanks everyone. I will check spark today. The Sniper does have AFR read outs. At cold idle it starts around 13.5 and slowly moves up to around 14.5. I havn't done full adjustments to WOT at all. I will look closer at it.
I set my warm idle to target 14.7. I know sniper is a learning system but know thats not perfect. I might reset the entire system and start fresh.
Will replace all my plugs and take heat measurements at the manifolds.
