Also -- check that your booster is okay. With the car running -- apply the brakes --- hold em -- shut the car down --- your pedal should hold for about 30 seconds is the booster isn't leaking.
So Check that....
Then --- you've got a couple options....
Increase your pedal ratio to 4:1 or even 5:1 ---- if you can keep all things aligned properly....
Add an electric vacuum pump .....
Or junk that set up and run a good manual master cylinder and get your pedal ratio to 6 or 7:1 <this would be my choice>
Or go to a "hydraboost" boost system....

What option would give me the best results? Manuel Brakes or an Electic Vacuum Pump setup with power brakes.
For manual brakes, i will need a special MC?
