pwhite, The Houston area Car Club Bash is this weekend (Saturday) at Lonestar Raceway just past Sealy off of I-10. There should be several cars from the Houston Buick Club there if you'd like to meet up with us. Gates open at 11am & it costs $15 to race or $10 to spectate.
I can also get you set up for the HBC email list, it's pretty much the best way to keep up to date with local events & you'll have access to some very knowledgeable Buick tuners from the area.
If you become a member you'll get a discount at several TR vendors (including our local guru Conley's Performance Plus,) Like I said just send me an email & I can give ya the low down about the club.

BTW, I hope you are planning to upgrade the fuel system to go with the bigger injectors & adj wastegate! FYI, there is a good how to at www.gnttype.org for making an adj wastegate rod.
