I would not see the point, there would be no to minimal power gain from switching..

I personaly would not go through the trouble of doing it. But the one way I can think of doing it would be to get a wireing harness and computer out of a MAF camaro/trans am.

Yeah, you can still find good tunes for SD. might aswell stay unique compared to the (lame) 94+ F-bodies :P.

By the way, join SpeedDensity.org, site dedicated to SD cars.

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).

For simple set ups, you can get good mail order tunes.
