Our  remote tuning device flashes the 997.2TT®  in 8 minutes and can hold up to 10 tunes at once. Not only does it keep the oem file but it also has a fail proof recovery method due to hardware failure. No need for unstable laptops and wifi to flash a tune.  . One can, at any time, go back to a stock tune  as many times as needed especially when the car is in for service.
