Dyno Tune Check List

Dyno Tune Confirmation Form

The purpose of this document is to inform you, the customer, about our dyno tuning policy and to serve as confirmation of your appointment.

Section 1: Tuning Related Risks

While we make every effort to ensure that the dyno tuning process is both safe for customer and the car we are tuning, sometimes there are events that are beyond our control. It is for this reason that we request that the customer stay behind the car on the ramp or in the TurboXS office during all dyno pulls. 

In addition, tuning a car on a loaded AWD dyno will stress your car beyond what can be accomplished under normal driving. Small installation errors or manufacturing defects will be magnified by the conditions we create on the dyno.

It is extremely important that you have very clear tuning goals before you show up at TurboXS. We will advise you on the reality of these goals and the risks involved, but you need to understand that if you are uncomfortable with something from a reliability standpoint or you do not wish to push for additional horsepower, you are responsible for communicating this with our staff.

Even given the best of tuning and the best possible judgment cars can blow up while being tuned. We do not push a customer’s car to the point of failure, but have blown up a few of our own test projects in pursuit of knowledge or the last possible horsepower for a given combination of modifications. It is our policy not to push a customer’s car to the edge, unless specifically instructed. In the event a engine failure should occur, we are not liable for the damages. This is at the risk of the customer.

Section 2: Pre-Dyno tune checklist

Before arriving for a dyno tuning season, please make sure you car is in 100% sound condition. We do not offer repair capabilities. We are a Manufacturing and Tuning Only. If installation of parts is needed please arrange to have them done previous to your appointment. 

Road Worthiness:

Make sure your brakes are in 100% working order. We will spend a great deal of time driving your car on the street after we are finished on the dyno and want to ensure that this part of the tuning process is as safe as possible. If during the course of the road tune we notice that your brakes are bad we will return your car to you without completing the road tune portion of the tuning process. You will still be responsible for the dyno time, but your car will not be finished until you deliver it to us with sound brakes.

Please check the condition of your tires. If we deem them unsafe, we will not drive your car on the road. You will still be responsible for your dyno time, but your car will not be completely tuned to our normal standards.

Check Engine Lights:

Please make note of any CEL codes you have before the tuning session. Please call TurboXS and discuss these codes with us prior to showing up for your appointment. We will then make the determination if your car can be tuned.


Please make sure your cooling system is up to the task of a dyno session. It is highly recommended that you run a 30% coolant 70% water mixture before showing up for your appointment. This will save you money. After each dyno run we wait for the coolant temperature to return to a reasonable temperature before starting the next run. If your car doesn’t make it back after a few minutes of waiting we will have to shut the car off and take a cooling break. If the car continues to overheat we will be forced to end the dyno session. 

Oil Level:

Please make sure your vehicle’s oil is at the appropriate levels. Also notify us is there are any oil consumption issues in advance.

Fuel Level:

Ensure that you arrive to the dyno facility with at least a ¼ of a tank of gas. If you are planning on doing a fuel switch e85, race gas, etc. This is the minimum we would like to start your tuning session. Additional wait time to refuel will result in additional fees.

Intercooler System:

Engine Tuning requires the car to be at the best possible condition before a session is started. Make sure you have checked your vehicle for intecooler couplers for tears, loose couplings, broken clamps and faulty blow off/bypass valves. These are things that should be taken care of previous to the dyno appointment.
