“Tuning is an art. To tune for optimal performance is to tune for a careful combination of speed, strength, and agility that varies as driver tastes vary.” -GIAC

Knoxville Performance exists to tune cars for the way people like to drive.

We represent the BEST software packages in the world.  We try each package on our personal vehicles before endorsing or selling a product to our customers.

We tune to your exact specifications using our state of the art all-wheel-drive Mustang dynamometer and the tuning program that fits your particular vehicle.  We rely on our years of experience and technical expertise to design a software program that is specific for your car.  If you’re not happy with the program and/or software you receive, we’ll refund your money and return your ECU/DME to it’s original configuration.

Don’t let someone “street tune” your investment or use their phone to show you how much horsepower and torque you are making.
