I recently installed the IBD plenum on my 06 Cayman S and was wondering if the sport button still does anything now that the stock plenum has been replaced. I also installed the Cargraphic exhaust system from the cat back and really don't notice anything different anymore with the sport button on or off.

Thanks in advance for the advice

 

doesn't the sport button change the ignition maps?

 

yes, and the throttle mapping & rev limit

 

Thanks....

 

I have the RSS Plenum and an AWE cat back system on my car. Pushing the "Sport" button still makes a NOTICEABLE change in the throttle mapping...The throttle is much more sensitive.

Replacing the plenum should not impact the sport buttons functionality. You should still notice a difference. If not, there may be an issue...
