Brakes Bad after S-TRIM install...HELP!!

[quick89gt]

Well, the car runs great, but unfortunately, the brakes are all screwed up. The pedal is really, really hard to push and it takes everything I have to get the car to stop. I checked for loose vaccuum lines and didn't see any. The only line I saw was the one coming off of the Brake Booster to the vaccuum tree on the firewall. I unplugged one of the lines on the tree and put a vaccuum gauge up to it...and it read 9lbs of vaccuum. Does this seem low? I obviously had to use one of the ports on the tree for my FMU and then the MSD-BTM spliced into that line also...and all of those connections are tight. So, does anyone have a clue what this could be???? Josh
