hey all, recently been having an issue where the car starts to go richer as RPM increases during WOT pulls. afrs go from around 11.4 to 10, to 9.7 as the RPM increases. i have cleaned the maf, replaced the seal between maf and intake, i have replaced to orings on my bov, checked intercooler piping and clamps, and smoke tested my setup. Smoke test did not show any leaks. Ive got a few logs here which all show the issue. any ideas what the issue could be? any help would be great, thanks!

the only thing I notice between these logs and logs where my AFR remains stable is the IDC being ramped up in these logs for what seems like no reason at all. everything else is the same.

Yes I have a log from the same tune before it started acting up. Will post it up in the morning. The tune hasn't changed and was done by a local tuner.
