drastic airmass drop under boost
E38 2009 ecu, turbo ly6, ever since going from 40 lb gm injectors to 80 lb SD injectors, in boost the airmass drops dangerously from 1.07 g/cyl for example at full throttle to 0.60 or even as low as 0.00 all while the tps is unchanged (83.9% WOT), afr commanded and actual also stay the same without issue.
Would the "speed density air mode" patch under the OS tab help out any or what exactly would that OS option do as opposed to being in SD/VVE only mode?
The link to my file and logs are below.
