Hallman Boost Controller Q&A...
I have the cockpit control and I put it in the glove box (because of the Police). You do not have to drill a hole in the firewall. If you look on the passenger side firewall there is a little rubber fitting that you can remove where there is already a hole. I just ran the cockpit control portion through there.
I believe it took me about 6 turns of the knob to get me to 21 and a half more for 22 psi, dunno if this helps anyone, but the way to the manifold is the best method yet, pulls soo much harder (btw this is with the hard spring)
