I have a 08 r6 with 43,000 miles on it. It's wnt idol at all, I can ride it, it runs, I just have to constantly be on the throttle, my best guess is a throttle body sync (which I think is supposed to be done at 26000 miles(mine wasn't)) but any way, when I changeout the header I noticed that inside the exhaust ports, cylinder 4 was much less burnt then 1,2,3 which also leads me to think throttle body sunk. Let me know what you guys think!

P.s. I just installed a power commander 5 EX and I have an M4 slip on
