After they strap the car down to the rollers, they will insert a probe into the exhaust for air/fuel monitoring, and a test lead on the #1 plug wire. After verifying the correct fuel pressure and bringing the engine up to temp, they will start a run up to a specified RPM. There is a computer hooked to the dyno that will tell the operator what your HP and torque was for the run. After analyzing the data on the computer, he will make changes to gain power and torque. Gains are different for every car it all depends on what you have on it like exhaust, intake..etc. I prefer a dyno tune because its catered to your car not a plug and play type flash that its generic, so your gains can be different from another car but both are stock.
There are other topics on the flash but WORKS so far i think will be the first to offer a dyno tune flash..
