I have extensions AND the big pass through sensors for about 15,000 miles.
So easy to Check and adjust pressure.
My sensors are off about 5psi but I use them as a differential safeguard and not as a precision instrument. Im not liking it, but it was an easy fix in my head.
Some here have a religious bent about extensions.
It is religious and not fact based.
When asked, they can give no support to their dislike other than dislike and theory.
Mazzillions of people have ran extensions since the first day of the inventions of the first valve.
