Yes but MAPs accounts for pressure and not air flow... Put a larger exhaust on a car with an AFM and the AFM will add fuel accordingly where as a MAP won't see the increase in exhaust flow and the car will lean out.
I prefer a MAP to an AFM but there are pro's and con's of both...
Adjustable gears are a good thing to have for tuning. Timing can make or break a car as far as what cam you want?
Duration and lift. Lift creates overlap which gives you the "blurp blurp blurp" idle. Overlap is good for rev's. Duration is what pushes the powerband higher, the higher the cam duration the higher your powerband will be and the higher your operating RPM's go.
Too big a duration and you may need to upgrade your springs and whatever else...
Higher cam duration means more exhaust flow which means you'll need a bigger exhaust housing on your turbo..
