What Is a Tuner?
A tuner improves your vehicle’s performance by changing the “tune” or performance settings programmed in its powertrain control module (PCM). It lets you replace the standard settings with a different “tune.”
How Much Does a Tuner Replacement Cost?
Tuners can cost anywhere between $250 and $1000. Factors that affect pricing include brand, series, and quantity. Professional installation can range anywhere between $400 and $700, depending on your vehicle’s specific make and model.
