Who needs a tuner? Well, at some point, anyone interested in building a quality, reliable performance car will. There is always going to be someone out there who knows a little or a lot more than you do about transforming a standard motor into a tarmac-shredding missile. An experienced tuner fully grasps "The Big Picture", of how everything under the bonnet works as a complete system, not as individual items. All this complexity makes tuning a modern engine more challenging, especially when aftermarket high-performance parts are thrown into the mix.
