This world is full of information about everything and anything. The way I see it is if were going to spend our hard earned money on expensive racing parts the user should learn how to make them function properly. The fact that the part has been produced means the hard part has been done already. Making tuning changes and logging runs is the best information the user could have. With the use of EGT meters and O2 sensors make tuning a lot easier than trying to read a plug.
Fact is none of us were born with this information already programmed into our brains. It must be learned. Depending on other tuners skills teaches you nothing other than depending on other people to tune your car.
