Before you get a car dynode, please check:

• the engine must be broken in
• have the tank filled completely up
• towing hooks must be installed, if they are missing the additional work may be charged
• check oil level and tire pressure
• the tires must not be damaged and have a sufficient speed index

A dyno run does not stress the engine more than a hard acceleration on a highway, but it is necessary to have the car in perfect technical condition for it.
