I got an adjustable wastegate from member OddMonte to put on a pretty much stock 1979 set up. The highest pump gas here is 91 octane. I will purchase a boost gauge to put on the A pillar. I don't even know what stock boost is. What do you think my max boost will be set at? I just posted a thread about 1/4 mile time estimate and it shows my stuff I'll be using. Not sure the add ons will make a difference in boost though.
