If you were to "dyno" your motor, or have it put on an engine dynometer, and change the components such as carb, ign, or camshaft,or their relationship to each other (adjust cam/valve timing "degreeing in the cam",ign timing, carb jetting, etc) then you'd be dyno-tuning the motor. Although it's pricey, it can be money well spent-especially if you run in a very restricted class. Nascar LMSC (asphalt weekly racing series) cars are very restricted and usually race engines which produce well under 400hp. Those guys will spend literally thousands of dollars dyno tuning, finding a very few ponies- and be glad for it!

An engine dynamometer is used for much more than just "bragging rights" about how much peak HP a motor makes. They are used for R&D, engine break-in, carburetor tuning and adjustment, as well as many other things.
FWIW, getting your engine tested and broken in properly on a dyno is not as expensive as you would think. From our experience, $300 is about the normal price. And for any serious racer not matter WHAT level of competition he/she is in, that is money well spent.
The dyno shop we work with here uses a Stuska engine dyno monitored by a DEPAC system.
Hope that helps.
