Bill,

My manifold gauge generally reads approx 1/2" difference between ambient and WOT indicating a 1/2" loss inMAP. But, am swapping out my old manifold pressure gauge as it sometimes hangs up at 20" manifold pressure. So not certain how accurate it may be.

Does anyone have a good manifold pressure gauge they want to get rid of? I'm looking for one, haven't had any luck on e-bay yet.

Rusty,

Call me crazy, but mine has always read the same as shutdown (ambient) when I go to WOT. My pickup is in the top of the stock lower half of the manifold. I have always taken this to mean no measurable loss through the 3-inch scat tube and large K & N filter.

Does anyone else have similar experience??

I'm still a bit concerned about the static MAP readings that I'm getting. This isn't something that just happened, but rather has been going on for at least the life of this particular intake setup. At on point, I was almost convinced that the TWM TB ports were just not providing an accurate reading, but now I'm almost convinced that they are. Has anyone measured MAP at WOT static?
