Now before someone starts typing in how wreckless speeding is, please just leave the thread. Anyways, I took my car on the EMPTY expressway last night and hit 150 for the first time, just to see what the car was like at it. Anyways basically right afterwards I got off the expressway and the rest of the night the car felt a lot more powerful, it even sounded different. Is it possible pushing it up to that speed allowed it to clean itself a little or am I making this up? My boss said he was told by a mechanic to let the car loose every now and then because the engine will clean itself out. I know it has an adaptive throttle and all that jazz, but it didn't seem like it was at all related, the car felt entirely different.
