Which one is more accurate? I have an autometer boost gauge and I have it plumbed into the plenum. My profec is hooked up like it is supposed to be according to version 1 in the book and the forum. Do a lot of you guys see a difference in the two? THanks.

should be relatively the same, but where the gauge is hooked to makes a difference. if its near the plenum, it should be close to specs, its towards the intercooler it should be a little higher.
