A little bit of both. It's a weird OCD thing where I can't get myself to rev past 3k RPM and giving it more than 25% throttle since it takes little effort to get to the speed limit. My coworkers poke fun at me for driving a sports car and not going through the entire rev range much. I try not to get negative attention from others by driving like a douche.
However, every once in awhile I do open it up when I can't bottle things up any longer. My heart beats really fast, palms sweaty... but after giving it a few good revs I cool down and feel much better.
