Strange problem with 6-71

Coyote Jack said

As I posted above, I do have power valves and the carbs are boost referenced. They were blower carbs from the factory. I like your idea of running a hose to my handheld vac gauge to look at while driving. It's a great way to check the mounted boost gauge I have.

What I have done is have someone ride along with you and record the vac readings at different times, like cruise and when you get on it then you can tailor your pv's to come in when you want, kinda like a fuel switch. I also mapped the vac readings thru out the rpm range, I like to have alot of data for some reason. And see where your boost is during the drive, too bad it is winter...
