Default APS 65mm nonuniform flow

Just ranting here, scaling OL is getting on my nerves, take a look at this graph, x-axis: MAFv, y-axis: g/s:

check out those wavy oscillations...

It took about 7 reflashes and 30 good logs to dial in flat 11afrs, not to mention stupid tactrix disconnecting for no reason (and ferrite chokes do not help on the usb cable, nor SSD disk where I heard it should help because it's not immune to g force as much as rotating disk)

At around 3.5MAFv APS 65mm flows less than stock by 4.1% , which is where I had most problems, getting 9.9-10.3afr instead of 11.

APS vs stock flow (Ctrl +, enlarge that thing):

I have very slight exhaust leak in exh manifold, could that skew the readings wideband gets? Or does an exh leak before turbo work like $0.00 ewg?
