  • When the GTS is run in AWD on the dyno it loads the belt between the rollers differently front to rear because the awd is not 50/50 on it. So it picks up the difference between the two and thus the wavy graph.*

Product Description

The Tuning Tech FS Cayman performance tune improves horsepower, torque, and driving characteristics by reprogramming the factory Porsche ECU inputs, air/fuel ratios. The remote tune is customized by data logging that can be peroformed at a local dyno shop, at the track, or on your favorite back roads. This allows us to customize the car to your specific purpose and need.  We ensure a tune that is not only specific to your modifications, gas blend and weather conditions, but rather your true use of it. You will not risk having to ship your ECU.  You can flash the car at your convenience instead of the mail man's.

NOTE: The customer needs to data log no later than 1 month from the purchase of the tune in order to receive a custom performance tune. Our software program allows us to keep your factory map at your finger tips and flash back and forth at your lesiure. Price includes shipping to lower 48 states.
