speed den to maf
I've noticed several people going in the opposite direction.
Specifically, tuning there cars with the MAF unplugged, then never bothering to plug it back in. (MAF defaults to speed-density if the sensor stops working).
It's been awhile since I read up on the pros and cons of each system. But I ended up coming to the conclusion that if I had the ability to tune the system, I wouldn't have any motivation to switch to anything else.
One possible exception is forced induction. But my memory is too foggy to recall why. And I wasn't dealing with an fbody back then.
Another is radically high-hp. And that would be a switch to alpha-n for a track-only car.

Because a speed-density system is sensitive to manifold pressure, and the stock setup incorporates a 1bar MAP sensor (which maxes out at 0psi boost).
