I've been looking into this myself. Seems if you do a regular rebuild, with a light bore, and trick bolt -on stuff like pullies , cold air intake, and a hotter ignition...speed density is alright. As soon as you talk street cam, increased intake bore - header sizing..and a set of upgraded heads...your into mass-air to handle it all properly.
There are people out there, who really know their stuff, who could maybe tune around speed-density...but mass air is the best way to go...just plan on it.
Interactive has got a bolt-on upgrade for $380. From there it's all +++ towards about $700 with-out getting trick stuff. Or, get a set-up off of a 88 to 93 with the 'puter, meter and harness used...about $200 up.
For a 'hot' engine, with bigger injectors, you really need mass-air and matched metering for the injector sizing...plus probably chip work for the 'puter.
At least thats what I'm getting from what people tell me, and I read.
