There's no secret behind making the power. All of these top tier tuners know how to get every last ounce out of these cars (All there is to adjust for power is IVO, EVC, Timing and Commanded Lambda) it's just a matter of where they decided to stop (for whatever reason) for the time they got to spend with the car. The driveability is the hard part on these cars. No doubt, put both behind the laptop, on a dyno and they will both post great (if not identical) numbers.
