No engine produces Horsepower. Rather, it is a measure of what you can do with the Torque it actually produces.
Producing Torque at higher rpm is good as it means you can exploit gearing to multiply the Torque and do more with it.

So: If you have 2 engines with identical peak Torque, but one produces this peak at twice the rpm of the other, it will be able to do more work as a any gear ratio you use to couple it to your load will be higher and hence have commensurately higher Torque Multiplication.

I did a shelf tune and gained 35 peak wheel and 40 peak tq along with strong sweet spot gains. I used OE tuning who tunes all my cars and I need to get the sheet from him. I can definitely tell the car jumps better than stock from a dig and roll and his throttle response improvements are great too. i did the tune with around 150 miles and now I have 700- very happy.

Their dyno operator and lead tuner, Mike, was the individual who tuned my S2000! The S2000 made 440whp/277tq.

I should bring my XFR there and see what numbers it would put down...
