Hi everyone new to the site and new to turbo buicks!!! looking for some help on tuning i just installed 42# injectors fuel pressure regulator a 60 series turbonetics turbo, boost controller and a new fuel pump.

base fuel pressure should be set at 42 to 43 lbs with vacuum line off and plugged [finger over the line usually works] boost should be around 15lbs on 93 octane with out a alcohol kit.On straight 110 octane you can run around 20 lbs boost with out to much worry.Take it easy on turning up the boost until you have the equipment [scan tool,knock gauge]to get a handle on what your car likes.Welcome aboard and try not to break anything to soon,that might turn you off to turbo buicks. george
