Apparently you do not understnd the difference between a flash tune and a piggy back. As stated earlier in this thread, a piggy back send false data to the comp through the sensor relays making the comp increase certain things such as boost. This has an end result of more power and torque in a roundabout way. A flash tune goes into your ECU and rewriites the data tables to give you a complete tune.
