DTC Removal
DTCs are also known as Diagnostic Trouble Codes. They are electronic messages in case of problems with the engine or transmission. They can be turned off when the causes are found and resolved.
FLAPS
FLAPS are small valves that vary the length/volume in the intake manifold to get a finer clutch and more efficiency. It is possible to remove or disable the flaps in the engine management system. Sometimes the valves break and when they do, there is a bigger chance of damaging the engine.
Vmax
Many cars have a Vmax, in other words: a speed limiter. It is possible to remove the Vmax from the car in order to experience the full potential of the car.
