Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Calibrating Pro-M Questions??

I have been having some problems if you want check it out here http://www.contour.org/forums/ultimatebb.php?ubb=get_topic;f=3;t=007324

So now I am wondering how you can tell if it is programmed for the right size injectors, even if you told them 19#. Also what did they do different during 99 that they would need my exact build date? What do they do differently in calibrating for an open air intake compared to the stock airbox. Thanks for any Answers!!
