Horsepower & Torque - How does each relate to acceleration potential?

After we figured out what was going on, we purchased JWT ECUs which increased the limiters to 7000-7200rpms and increased midrange power by 10whp/wtq and increased peak power by about 5whp/wtq. The extended rev limiter allowed me to take full use of the increased power which was now much stronger than stock especially considering the fact that the increased limiter allowed for rpms that once weren't utilized. Theorectically at 7000rpms, my VQ30 was making about 70whp more than stock if I could have taken the stock motored dyno to 7000rpms. On the track, the car went from consistent 14.6-14.7@96mph to consistent 14.3-14.4@99mph.
As you can see, it took a crap load of power above 5800rpms to make my car go significantly faster. This mod alone allowed me to understand just how important it is for mods to increase overall power, just not peak power.
