aps 70 mm & DW 850..
so a friend of mine has the aps 70 mm intake along with dw 850 inectors.
tried to get maf scaling dialed in but had a few issues.
dw 850's are modded stockers so injector latency is the same.
but flow is bumped up from ~500 to 850cc.
so now with larger injectors & intake maf scaling is the issue.
tried injector flow rates from 680cc to 850cc to
get the afr's at idle close to 14.7, so i could then "adjust"
anyone encounter same issues?

Latency should be adjusted to bring the idle fuel trims in line.
The best option would be to revert back to the stock air box and tune the injectors than swap out for the APS intake.
