How hard on your motor is it to have it dyno tuned ? I know it is much better to tune the motor under load but I have also heard that it is quite hard on it. Is this true ? Also, what questions should I ask the shop to determine if they are any good and know what they are doing as opposed to just running it hard and finding out how much power it has ? Basically, what are the things I should be looking for when doing this ?? I am looking at JBA racing in San Diego. Has anyone ever used them ? Thanks in advance.
