Let's not immediately assume that the drop in boost is a "chip thing".  IME, 
most drops in boost occur from either high charge air temps (heat soaked 
intercooler), or from high engine temps.  Both these inputs to boost will 
revise the boost threshold, especially in the chipped cars.  Heat soaking 
stock intercoolers on chipped cars, especially k24 equipped 200's/S4/S6 20vt 
cars can happen in a matter of a couple hundred feet, btmt.
