https://www.youtube.com/watch?v=c9yDNlU_Y68 in this video engine was stock with stock coils stock cams, spa cast manifold, s366 billet turbo, 4 inch exhaust aem v2 ecu and usual modes for that setup, after that i did full engine built with gsc s1 cams and springs, lq9 coil kit, that spots was sorted until i split engine again duo to head lift, now everything is back together and i have same spots again, i try to use different plugs but no changes, as you can see afr is not changing on that spots, boost is not dropping, anyone have any idea?
