Probably means different things to different people. To me power shifting has always ment shifting under power ... you shift without taking your foot off the throttle. If you're gonna do it, make sure you know what your doing because its hard on clutches and transmissions and rear ends and drive shafts and spider gears (learned that one from replacing them a dozen times) and if you miss a shift with your foot to the floor its hard on engines (thats what rev limiters are for !) and its hard on your ego when you do it at the strip
