Depends on the platform, what the car is already running, and whether it's a dyno tune or an e-tune. Send us the year, make, model and current mod list and we’ll come back with a real number instead of a guess.
There’s no honest flat price on a build. The parts, the supporting mods and the state of the engine all move it. Tell us what you want out of the car and we’ll spec it out and put a written quote together.
Our shop rate is $125/hr. For a build or a specific job, get in touch with the details and we’ll put together a real number rather than a guess.
Performance is the focus: ECU calibration, Holley EFI and HP Tuners tuning, full builds and race car builds, suspension upgrades, fuel systems and electrical systems. We also run trackside support. If it makes power or puts it down, it’s us.
On a car still under factory warranty, modifications can affect coverage on related components. We’ll talk it through honestly before anything gets flashed.
That’s a lot of what we do. Modified cars break in ways a dealership won’t chase. Send us the details and we’ll tell you what the last shop got wrong.
