This long (a bit over an hour) but super informative video will show you exactly how to tune a Buick Grand National, Turbo T, Regal T-type, etc.
It covers the basics for a TurboTweak chip and AFR (Air Fuel Ratio) tuning.
Watch the video, go tune your own Buick Turbo Regal, and see it run better than ever!
This is probably THE BEST video I have ever seen for how to tune these G body Regals!
