egladman is on a distinguished road

Ok I took the car for a drive tonite and everything was great. Power back to the usual. Would a difference in outside air temperatures make the fuel pump act differently? Also the BCS is shot. I finally got the bypass trick working and I had boost. Hooked up normal and I'm only getting 2-3 psi. Now all I need is my $1600 so I can start modifying this sucker.
