I called Racetronix once looking for some info on a sending unit for the Buick and had to leave a message.
Jack called me back, answered all my questions and then gave me the run down on what upgrades to do first on the car.
(TT chip, hot wire kit and all that kinda of stuff)
I'm not sure he was going to sell me the part I wanted, but he said I could pay the vendor and he would drop ship it and maybe save me a couple of bucks.
Ordered, received, installed and all worked well.
