i appreciate all responses and advice...
Do yourself a favor and disregard the boost gage inside the tach. It is fairly useless as it is inaccurate. Its hard to see as well.

The best thing to do is buy a VDO mechanical boost gage and install it in the clock location and tap into the brake booster line for a signal. Way more visible and 100% more accurate.
There is plenty of posts here on the forum discussing this gage and its installation.

You will be amazed at the difference in behavior of the 2 gages when you compare them while driving the car. The stock one you are correcting with the sending unit is way off.
