Heyya Azine,

I've been looking at my wideband recently between shifts and I've noticed that it seems to get pretty rich under normal driving when between gears.
When cruising its around a steady 14.5-14.9, but when I push the clutch in and change gears it seems to dip into the 12's or maybe lower.

I know this is normal under WOT, but under regular driving I dont recall the car doing this before.

I checked the fuel trims and the LTFT partial is at -14%. I am on week 2 of a revised tune, it seems to be running fine aside from this issue. No codes present.
Fuel trims werent this high last week when I checked.

If it was a boost leak, wouldn't I notice it during cruising too? Is there an injector dwell setting for between shifts?

Any ideas before I pressure test later tonight?

Thanks
