Myth: The best tuner can install one tune with optimal results.
Fact: Although generic tunes can perform well, in most cases they are not optimal no matter who you get the tune from. Results vary in different vehicles as demonstrated in these charts. These boost charts were obtained by engine logging. Logs assist a professional tuner in diagnosing engine problems and fine-tuning your ECU. This is essential for true custom tuning service. You will get optimal power and optimal engine life.
Myth: A generic tune works equally well in all elevations and climates.
Fact: Turbos are at greater risk of failure at high elevation. We take into account the client's elevation or atmosphere pressure while creating every tune. Boost will automatically be reduced if you drive to higher elevation. Hotter weather also contributes to warmer intake air temperature and warmer exhaust gas temperature, which affects engine or turbo reliability.
Myth: A tuning box has the same level of adjustability as an ECU custom tune.
Fact: With a tuning box you can adjust boost or fuel quantity in the entire rpm range, but that's where its limitation lies: Your boost+fuel cannot be adjusted at certain RPM points, see the following examples:
