Well for shift points your right about higher rpm, I don't let it get below 2k without down shifting because they just don't like lugging and chatter like a thrashing machine. My target cruise rpm is 2500-2800 up to 3200 with the powerband starting to dwindle down around 5k. Before I started chasing anything eels I would grub the shift recommendations from your owners manual and try those for a whole and replace those wires. I've been knocking out some miles today on my 04 and I could classify it as a lil sluggish around 1800-2k when I hit near wot. How did your plugs look when you pulled them. Or, if you have 2k on them how are they now?
Now, about that air box. Left, I can't make out the pic. Have you replaced it with a ness KN out similar or is stock box on it?? I know you have KN on your sig but wasn't sure stock box kn or ness big sucker replacement. Wires, order them now! Rule out what's sure to need replaced. 11 years? Yes.
