Bad MAP??? What should the range be?

Currently having issues with a huge cut out under WOT or actually anything over 1/3 throttle.

My MAP reads around 4.4 to 6.5 at cruise and never gets over 20.4 under throttle (but can't get to far into throttle as my timing gets pulled down to 3-4 degrees under accell, makes for a serious bad bog). So the question is, what should the minimum MAP reading be. From what I have read it is supposed to be 10 kpa and above. Bad MAP sensor?

Any help is appreciated.


Any other possible reasons why the MAP would be reading so low other than just a bad sensor?

Thanks much
David
 


Yeah, sorry, should have stated that earlier. It is an L67 out of a 01 GTP with vs cam, intercooler (short stack), 3.4 pulley, headers, springs/retainers, ported/polished throttle body, Intense PCM.

Thanks
