the biggest difference i noticed with the stage 2 kits was the consistant power where-as 450 feels really slow after youve driven hard on a hot day, when i did track days with the 450 the heatsoak made the car feel as slow as stock after a long day at the track, with 500 it always feels fast......

450 to 550 would feel insane!!!! 550 is only available for the european owners however tom could easily run this as he has meth in place which simulates an effective 110 octane......
I COULD if I could afford to run about $5/day to refill the meth since I drive it so much...

415 should be with the 7psi kit. Im gonna dyno my 8psi in a few weeks
