Some Turbo Buick owners have a scanmaster installed in their G-body Regals and aren’t quite sure how to actually use it properly to tune the 3.8 liter turbocharged v6 engines that make these cars what they are.
The below photo tells you exactly what you need to do to get it running the best it can be.
I’m sure there are other fine tuning details that can be implemented to make it even quicker, but this is a great start onto that journey.
(I forgot where this pic actually comes from, as I have a lot of reference material, but thanks to whoever made it!)
