93 speed density tuning
thanks all in advance..
If you're not looking to do a lot of tuning, just stick with the mail order tunes or find a local tuner/dyno that can still do chips for you.
If you're looking to upgrade the PCM, there are writups on doing the wiring to the obd2 lt1 late models, or you can jump over to a modern Holley system that will lighten your checkbook but allow most novices to tune.
