Not sure who the OP are or what their reputation is but it's likley to just be an opensource 16-bit Speed Density patch, created by carberry.
Only avaialble for 16-bit ECU and flashed using ECUFlash or ECUEdit.
Just google Speed Density Carberry will give you more info.
There are other patches for launch control and FFS (Flat foot shifting) that don't have the Speed Density (MAFless) patch.
I don't recall seeing anything for Anti-lag though as suspect not possible on conventional (Non-DBW) throttle/ISCV due to lack of airflow.
