What this tune does you the 997TT is amazing. It not only adds significant power, but also smooths the lower end of the throttle range. The car is much more drivable with a very big surprise when you floor it. This is really what the car should have been from the factory !
My story is a little convoluted as I had first installed the tune, then added the FabSpeed performance package later. A long story but the shop that did the exhaust damaged a 02 sensor, triggered a CEL, then replaced it with non-OEM sensor. Several O2 sensors later a OEM was installed and the CEL was gone. Make sure you always use the OEM O2 sensors.
Before the FS system the car had been transformed. I was not expecting the exhaust upgrade to add what it did. This car is a rocket that seems somehow tame and docile.
During the O2 sensor debug I restore the factory tune for a week. It is easy to switch and amazing to see the change with 5min of flashing.
Many thanks to Dan for the great service and price. This is the by far best thing you can add to your 997TT.
