WhooHoooo Man I just got done installing the performance tune and WOW it's really a noticeable change to the SOTP meter. This is a really neat product, the installation was a breeze, "Key On", "Key Off", "Key On", "Key Off". The car ran just smooth as could be and then at WOT she just noticeably pushed the front of the car up and just screamed. Haven't had a chance to datalog or anything else, but I can say the canned Performance tune that comes with this thing is the real deal. I feel like I've got that dumb a$$ grin on my face again like the first time I rode in the 03.
