The problem with speed density is it doesn't measure the amount of air that is actually entering the motor, it calculates it. Speed density is best if you go standalone which use speed density and u fill in all the maps. The advantage is u can fully tune the motor to get it to do exactly what u want. You can get away with staying SD, but u'll have to run some kinda standalone set up so u can tune it. Otherwise u'll never get away with runnin a supercharger sd.

Id just spend a few hundred bucks on a junkyard MAF setup and be done with it.
Theres alot more choices for cams and other performance parts with a MAF system.
