I've decided to sell my BSTC in favor of a Hallman. I installed the unit in my car and do not wish to pursue dual solenoids to make it work correctly. It comes complete with the instructions. Pics available on request.
Thats a Great price! I have had mine for years & it works well. With alchy you dont need 2 solenoids. Set it to 21-22 baseline & you have 6-7 lbs adjustment on 1 solenoid.
