We strove for a compromise when writing our tunes between performance, efficiency, and longevity. Which is why you will typically see our tunes have better power throughout the entire power band, sacrificing a few HP/TQ here and there for efficiency, longevity, and great performance throughout the entire RPM range. Also, our tunes are not "canned" tunes, each tune has been specifically tested on a vehicle with those specific parts on a dyno to provide the best possible tune (short of a custom dyno tune, which costs hundreds, sometimes thousands of dollars). Some tuners tune to the ragged edge of the vehicle's limits, we do not. We have (arguably) the best tuner in the country. We also provide free tune updates for any future mods as long as you purchase the parts from us.
