A person who compares themselves to Competition motorsport engine & electronic calibrator. Typically known for social media popularity, disabling important engine fail
safe parameters such as detonation (
knock) sensors.
These individuals lack the mechanical and electrical experience of working on
said competition vehicles. They do not own level C (or better) technician tool boxes, completely incapable of tearing an engine down & putting it back together to
even the simplest OEM specifications.
Typically these “tuners” carry themselves with a high pride in their “flame maps” and “gapping” the competition. When they in
fact cannot even gap piston rings properly.
