The Porsche 987 3.4l Cayman Boxster s is a load of fun to drive and out shines its competition in class. With some additional programming to adjust the cars timing and air fuel mixtures, we are able to gain improved performance on the 3.4l engine. The biggest difference when you flash the 987 is the overall improvement of the power curve. The car has much better throttle response whether the tiptronic or 6speed transmission. Where the car is sluggish off the line, the newly flashed car picks up right away and pulls harder through the mid and top end rpm range. Overall, the daily driving characteristics are vastly improved while providing you additional benefits that the Porsche 987 craves for.
