Re: Porsche Sport Mode retrofit or Sprint Booster?

Thrilled with my Carnewal GT Exhaust on my 2011 PDK Cayman. Next mod - the Porsche Sport mode software (@$1300) or the Sprint Booster (@$300). Thoughts?

2011 Cayman (Platinum Silver/Black)
Previously owned:
2001 Boxster (Seal Grey/Black)
2005 Carrera Coupe (Arctic Silver/Black)
2005 Carrera Cab (Arctic Silver/Stone Grey)

I had the sprint booster on my 2002 S. It has 3 settings. The only problem I had was finding a good place for the switch. Don,t know that it made the car faster but the throttle response in the 2 active modes did change.
