First I should start of by saying hello and great forum, seeing as I am a new guy. I have been around Turbo vehicles for years now, everything from turbocharged snowmobiles, to cars (Subaru WRX). But now have made my way into the diesel community. The lack of a throttle body like gassers still baffles me a little?
SO HERE IS MY QUESTION: 1995 F250 7.3, I just installed a standard Autometer mechanical boost gauge on the steering collum. WOT I hit stock target boost of around 19psi I think, but the needle is bouncing or twitching +and- about a psi I can barely read it!!! My line is tapped into the MAP sensor line that runs from the right manifold to the MAP mounted in the firewall. Is there a more stable boost source to view?
I have searched but havent found an answer in old posts, but I am sure someone has adressed this before and how to correct it, becuase its rather anoying!!
