This time I want to share my experience fitting a CDA on my GT.
Despite all I have read, I found it quite simple: I mean, itīs necessary to remove the under tray but beside that everything was simple as shown on the pics. After removing the filter box there was lot of room to fit it. Just need a small couple (shown on pics.) in order to fit the sensor, the rest was simple as fitting instructions said.
The result is quite satisfying, with a faster response of throttle and a minimum but noticeable power gain. As soon as I take it to the dynamometer will share the numbers.
