Just did a MHD logging run with the parameters available without the MHD flash (forgot to enable the HPFP parameter), i felt a slight hiccup around 2900 which can be seen here, any idea what that could be?
Zoomed in view of the hiccup and AFR changes in that moment:

Also noticed AFRs don't drop to ~235 when releasing throttle very quickly and not both banks, could that be leaky injectors or maybe bad O2 sensors on the donwpipes?
Forgot to turn the DSC off though, but doesn't look like it intervened anywhere apart from a random throttle dip.
Car is stock apart from an upgraded charge pipe, coilpacks are 2k miles old, spark plugs around 10k miles old.
