Turbo kit all put together and running good. Had to get the smaller brake booster from zzp to fit the 3" DP of course. but now the brakes are ROCK HARD. It stops, but with an insane amount of effort. First though was to bleed the brakes, no change. Couldn't figure anything else out so I took it to the performance shop we have here in Albuquerque to let them tinker with it. After a few weeks they're now telling me that I don't have enough vacuum at idle for the brakes and said I need to install an electric vacuum pump. they told me that when they add more vacuum with a pump the brakes come back and work normally. Anyone had this problem before? Is their another way to fix it besides spending $400 on a pump?
Thanks.
