Bobby, if you can please try the test I described using a hand held vacuum pump as I'm quite certain the MAP input you're seeing at idle is the cause of your rich fuel mixture. Please try and see if the gage and your MAP reading on the laptop agree while applying vacuum to it...you can do that with the engine off. If they are off by a wide margin then there you go, if not then please post up the results of bringing the MAP to around 40ish with the engine running and see if your pulse width number decreases. Joe
