Pre-Dyno Maintenance Checklist

Even if we haven't worked with you before, you can schedule a dyno service with us. However, we encourage our customers to run a Pre Dyno inspection before service to ensure maximum performance.


Make sure all fluids are at the correct operating levels. It will primarily include engine oil, transmission fluid, brake fluid, coolant, and if applicable, differential/transfer case fluid, clutch hydraulic fluid, etc. It is a good idea if you haven't changed your oil and oil filter for 3,000 miles or more, to do so before coming in. Please bleed the coolant system before arriving for your set appointment.


Be sure that your vehicle can run at the correct operating temperature. If your car is experiencing overheating issues, we won't be able to perform a dyno service on your vehicle.


Please arrive with enough fuel to complete the dyno service. As well as, make sure that you are using the correct fuel octane for the dyno service.


If you currently have a check engine light (CEL), service engine soon (SES), or Malfunction Indicator Lamp (MIL) on, please do not schedule your vehicle for dyno service. A vehicle must be free of these warning lights and be mechanically sound before we can perform a song.


Make sure that before the visit, you have an electrical grounding that is sufficient. We recommend that if your car is over five years old and has exposures to humid climates, you must clean your engine grounds and attachment points.


Are your battery and alternator functioning properly, and supplying power the way it should? If not, it is a good idea to replace these beforehand.
