untunable car 2013 n55 pwg

i am starting to believe that my car is un-tuneable. active autowerke tried flashing with almost no avail. boost not hitting target, the biggest difference I can feel power wise is when I custom tune my map 6 JB4 on top of the AA flash tune. even with that though I'm still getting the occasional AFR leak code and I'm not hitting Seth targets, I've confirmed there are no boost leaks or fueling problems, here is my mod list, jb4, AA flash tune, fuel it s2 lpfp, CP, DP, FMIC, full dp back 3.5 straight pipe, pure stage 1,xhp stage 3, drop in air filter.
if anyone thinks they can JB4 tune my car any better be my guest, as far as I'm concerned there is no one out there that can fix this problem.
