Help needed! Misfire or hesitation

Quick update. And many thanks to Colin for showing me how to swap those coilpacks over. Most apprieciated! :thanks: :) If you're techie no-hoper like me .. then anything mechanically technical sounds like major surgery.

 

With the new coilpacks it's still showing the same misfire. I've got some new Denso IK24 coming - and have a go swapping those over.

 

I know the SAFC-2 isn't yet setup on the rollers - and is running rich. My AEM AFR gauge goes to 11's and sometimes off-scale on full boost. So, possibily the rich AFRs on full boost have fouled the plugs causing the misfire.

 

I plan on getting the car to Phoenix in January, to have some toys fitted and then it'll be off to Thor.
