If you put a "T" in the vacuum hose that goes to the waste gate, then put another vacuum hose on the T running someplace where you can adjust the boost by opening the bleed-off on the bubbler. Thing is, you have to be careful because boost without fuel is very bad. That is why I used the MP computer, it brought the boost from 7 lbs factory to 11 lbs, and ensure enough fuel that we ran a 180 thermostat and 14 lbs of boost all day never hurt anything. We did this to a few turbo cars, never hurt anything.
