Hi There,
Putting a supercharger on a Tahoe/Yukon/Sub is something that is common with all of the aftermarket converison companies (AI, Canepa, Becker etc.) but some people have had a lot of trouble with the installation and maintenance. There are several brands of superchargers that people use and it looks like Whipple tends to be the brand of choice.
That said, I recommend going
here and doing a search (Ctrl+F) on "supercharger" and see what people are saying, pros and cons.
Good luck.
