Only the manual A01G rom was patced by ztan for speed density
if your car is auto A01I then there is no speed density patch available for opensource tuning .
You can tune for boost without SD but on a standard diameter maf tube your limited to about 10psi or so before maf maxes out.
Then you have two options, use a maf sensor from a wrx\forester turbo car its plig and play will give you about 30% more maf reading ( will need recalibrating)
or go to a bigfer maf tube diameter and rescale stock maf sensor for that
otherwise if you must have SD your going to need to use ecutek system instead but more expensive
