Looking at an 05 that has an 11:1 piston and mild port on head. Everything else is stock. Couple questions, what kind of performance bump is this and what would be the next things to change? Also, what performance differences are there between the 04-05 and 06+ ? Thanks for all the info, changing from a 400EX
