What Customers Are Saying
Customers choose The Tune Shop for clear communication, application-specific guidance, and calibrations developed around the actual vehicle rather than a generic one-size-fits-all file.
Why Choose The Tune Shop?
The Tune Shop combines platform knowledge with personal service. We verify compatibility, keep licensing and controller services transparent, and develop the calibration around the vehicle's real configuration and intended use.
Tuning Options
Base Tune
A custom calibration developed for your specific vehicle configuration, supported modifications, fuel, and intended use. Base Tune provides the initial custom calibration without the complete datalog-based remote tuning and revision process included with Remote Tune.
Remote Tune
Our complete remote-tuning service. Your calibration is developed around the vehicle's actual combination and refined using requested datalogs and calibration revisions as reasonably necessary to complete the initial tuning process.
Remote Forced Induction Tune
Our complete remote-tuning service for applicable aftermarket or substantially modified forced-induction combinations. This option includes calibration development, requested datalog review, and revisions appropriate for the supported turbocharged or supercharged combination.
