How much hp do you actually use?

I use all of the hp (albeit briefly) whenever the road and traffic conditions allow. When I get on a nice long onramp to a relatively empty freeway, I just can't resist the temptation to excercise the upper limits of the rpm range.

In order to use all of the hp for more than brief spikes, you'd have to have the ECU reflashed to remove the 112 mph speed limiter.
