I am curious what the boost was driving around town before the tune. I thought stock max is 8.8 PSI. Having higher levels of low psi will make a difference over time, though not as much as peak. There is no such thing as something for nothing. All the tunes increase power and torque throughout the RPM band. Driving mild will help, but don’t think you will not have extra ware and tear.
