Hey everyone :cool:

I have been trying to troubleshoot my issues for months and wanted to get some fresh eyes that know this platform better than I do.

Some background:

Modlist: Whoosh V3 intercooler, Mountune Radiator, CPE RMM, New Ford OEM Top Motor Mounts, Drop in Air Filter (cut the bottom of the air filter off for sound :whistle:), NGK Ruthenium HX .028 Plugs, Mountune Silicone IC Hoses

I did a timing belt & etc, about 2000 miles ago by a local small shop.

I purchased a Dizzy Stage 1 Tune and drove it for 100 miles. My OAR wasn't getting to -1 so this is when the troubleshooting began. I tried a ton of different gas stations, ended up getting my intake valves cleaned professionally which seems to have helped my OAR.

My Issue: I am getting a ton of negative corrections / knock at WOT. I removed the tune to be safe but I am still seeing these corrections on the stage 0 tune. I have been triple checking everything is tight and good, the car itself drives and runs fine, no CEL or rough driving. Hits peak boost fine. My OAR drops as well when getting into WOT with the tune.

I attached a log of some WOT with the tune, car doesn't go into corrections until I am at WOT.

Does anyone have any advice of next steps for things I should be looking at? Injectors? Boost Leak? Timing?

Thanks everyone, hoping I can get this fixed and start enjoying the car again.
