assuming that the profec is installed correctly, the main thing to guess at is the midpipe. most people find they have creep unless they enlarge the wastegate. it depends on your car and your components as to if you get creep or not.

solutions: either englarge the wastegate or go with a high flow cat

You can try tuning the boost down so when you creep it won't go as high ie set boost for 8 and let creep to 12.

Temporary solution...best bet is to enlarge the wg.
