When talking about vehicles, a TunerCar is a vehicle with modifications and replaced OEM (original engine manufacture) parts. Sometimes swapped with custom or performance oriented upgrades or even changing parts to make a more powerful and efficient vehicle; tuned. Most have a form of forced induction and go pop whilst shooting aggressive flames! Usually seen on the streets as opposed to official race tracks. As of 1995, production vehicles must meet the OBDII protocol and thanks to this advancement in technology, most modern day vehicles can also be tuned (optimal programming values) via Software adjustment. This is also considered tuning of TunerCar's.. Major gains can be implemented via software modification. After mechanical(hardware) upgrades and custom software tuning (a computer flash) to supplement the new vehicle characteristics; YOUR CAR WILL DESTROY THE ROAD AND EVERYTHING AROUND IT!!! {your fines will cost as much as your dyno flash bro} We us the word "tune" -> "to adjust" or "to change" something from factory specification. Word on the street: People call fast Japanese cars "tuner cars" People call fast American cars "muscle cars" if you want street credit - get street credit
