more info about the car...?
Are you bleeding boost off from the MAP?
If its a greddy kit, it sounds almost like the blue box is wired wrong...
EDIT: ahhh, is it a drag gen III kit? If so, I am VERY curious as to what you are doing for fuel as well, stock GSR injectors suck.
Make sure that boost is bleeding off before the MAP sensor, that sounds like the problem. double check that everything is plugged in, and the vacuum is all correct, what kind of vacuum is it pulling at idle? fuel pressure? sometimes new motors have a lot of 'junk' in them and it takes some time for them to run well (shouldnt be more then a few miles)
are you getting a check engine light?
