OK update.
I have stuff from Baer as mentioned earlier to display.
Hartline Performance is sending out some stuff for display as well. Keep in mind Cal is coming out here in April so you can get a good deal on a FAST unit and he can tune it.
I have confirmed that Mike from TA Performance will be showing up. Not sure of what all he is bringing yet.
Pete from Alradco will be showing off his radiators and LED kits for the Buicks.
I am still working on a local turbo vendor showing up as well. Not confirmed yet.
