you might not have a hp problem---

A speed problem in the area of 10-20 mph from expected performance can many times be traced to alighnment, dragging brakes, unusual aero drag, slipping clutch, or letting off the gas and early braking

Let some one else drive the car so you can see whats going on with it and get the second opinion

One of my friends pro-stock Camaro( 1980's) had such a screwed up suspension that it ran over 15 mph faster after a set up

Check to see how hard the car rolls by gently pushing it on level ground , straight ahead and in a rt and lt turn
