It is not a easy as just switching out the tune.. My suggestion is to revert back to stock then complete at least 3 drive cycles.
Drive cycle:
The recommended OBD II drive cycle begins with a cold start (with coolant temperature below 122 degrees F and the coolant and air temperature sensors within 11 degrees of one another).
NOTE: The ignition key must not be on prior to the cold start otherwise the heated oxygen sensor diagnostic may not run.
- As soon as the engine starts, idle the engine in D for two and a half minutes with the A/C and front and rear window defrost on.
OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.
- Turn the A/C and front/rear defrost off, and accelerate to 55 mph at half throttle.
OBDII checks for ignition misfire, fuel trim and canister purge.
- Hold at a steady state speed of 55 mph for three minutes.
OBDII monitors EGR, air pump, O2 sensors and canister purge.
- Decelerate (coast down) to 20 mph without braking.
OBDII checks EGR and purge functions.
- Accelerate back to 55 to 60 mph at ¾ throttle.
OBDII checks misfire, fuel trim and purge again.
- Hold at a steady speed of 55 to 60 mph for five minutes.
OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.
- Decelerate (coast down) to a stop without braking.
OBDII makes a final check of EGR and canister purge.
- Test complete

IMO it would be easier to just pay the dealer for the service. WOW!
