I called a couple of times, but didn't get a hold of anyone. Then I had engine issues and my truck sat for a while. I may try again now that it's running good again.
Possible FMIC. There is a shop in Tooele that does real nice stuff for the turbo Buick's. I just never got a hold of anyone last year before I started having issues. I forgot about it actually. I will start looking back into it this week.
I know RJC racing well, and can vouch that they have good stuff for the Turbo Buicks. Most of that crowd has probably heard of them. Good luck with the project.
