I love it. It's perfect for me and how I drive. Like D90man states, it pretty much kicks in after 1/4 throttle. It gives the torque and surge I originally expected out of the 335i but didn't get. Fun as hell to drive around town even at low speeds. You can feel/hear the extra growl it gives. No issues at high speeds either (cruising at 140 mph on the autobahn) and I never have an issue with my engine overheating. Bottom line: get it. I may later get the ProCede but TT is performing exactly how I want it for now.
