Our Dyno

We tune on a Mainline ProHub 3600 AWD dynamometer. Mainline is the gold standard for tuning and their ProHub offers you quite a few benefits.

Our Tuner

Kevin Nash, or K-NASTY, is Circuit Demon's in-house shop tuner. He has been providing professional tunes since 2016. Kevin has tuned hundreds of vehicles ranging from imports to domestics, including Subaru, Mitsubishi, Chevy, and more.  Kevin highlights his work on various Subaru's from mild to wild. He prides himself on being conservative with his calibrations to retain the reliability of the vehicle while maximizing your cars capabilities.

Disclaimer

Prior to your tune, we are not responsible for checking spark plug condition, engine health or any other major components that may fail on the dyno.

If additional mechanical work is necessary in order to complete the tune after the car has been started, we will charge our normal hourly labor rate of $150/hr to diagnose and correct issues before the tune can resume. This may result in you missing or forfeiting your tuning slot until the vehicle is returned to a mechanically sound state.

Tuning on the dyno WILL push your vehicle to its mechanical limits. As the owner of the vehicle, it is your responsibility to ensure that the car is mechanically ready to handle the stresses that will occur as its limits are reached. Circuit Demon is not responsible for any damage to your vehicle incurred before, during or after your tune. Any damage to the engine, transmission, clutch, driveline components, etc. is the responsibility of the vehicle owner. Circumstances above and beyond the control of the tuner and Circuit Demon can occur during or after the tune which can affect the engine or cause engine failure.

By placing the deposit you acknowledge that Circuit Demon has outlined the potential risks involved with dyno tuning and running your car on our Dyno. You waive any and all claims against Circuit Demon for any damage to your vehicle as a result thereof.
