I began this site several years ago to help those turbo Buick owners that want to learn how to both maintain and tune their cars.  Much of the content comes from not only my own experience as an owner since 1986, but also from the shop manual and online forums like GNTTYPE.ORG which began as a mailing list long ago.

Most of the information contained here is for intercooled cars.  Having never owned one of the earlier cars, I know very little about them, but what little information I have collected on the '84/'85's is presented in it's own section.

If one wants to fully enjoy ownership of one of these cars, it is a necessity to gain an understanding as to how things work.  Otherwise it can be a painful and expensive undertaking.

Questions, suggestions, corrections?  Contact me here, Steve W.  Remember that if you cannot supply scan tool data, I am only guessing and that is not very helpful.
