106700, is my HAHN Fuel mapper going bad???

Is this a sign of FCD going bad?
at WOT I see
6lbs. on the boost gauge
about 80 psi on the fuel gauge
feels and sounds like it being held back
if I snap the gas it clears somewhat.
also would a failing FCD trip the CEL for the MAP sensor?
as of now I have no CEL but I am sure if I keep it up it will trip a 43

it is possible, personally if you have a 96+ yr, i would rec using both an FCD and a missing link... contact mike eclipse982nrRST for a replacement FCD, and ive seen a few missing links hangin' around the F/S forums.
as for the the PCM seeing higher then 4.7+ Volts, you will notice terrible bogging, and no power.

This is the first I've heard of using both, whats the story behind that? I thought just one was good enough.. I use the Symtech FCD and have no problems
