This is common when there's more power in the mid range. The car will be faster as there is more power under the curve. Dyno your car and drag race shifting at redline, then shift at a point that yields the most power. I promise you that the shift points will be crucial in finding speed and keeping temperatures down, yielding even more power for longer.
