Fixing the air box issues and the secondaries is really a common need, people do stupid things to their bikes. But, the stock map for my 06 is horrible, especially the power commander crapola. I'm still running the Big B map in my 2006, still runs fine after all these years. Still on the original coolant hoses, but I have changed the vacuum and fuel hoses. Probably will need to change the small fuel hose on the injector rail again, but so far the "new one" I put on years ago is not leaking..... and I need new brake hoses but I haven't bothered with it yet, it kinda stops okay. I resisted doing the TRE thing for years, but getting full power in 6th is really nice. Much less shifting and I also dropped a tooth off the rear sprocket when I needed new stuff anyway. That bigger chain is still going strong, the 530 conversion and a little lower gear ratio was well worth the trouble for me. Oh and the auto chain oiler! Messy but man it has kept my chain looking like new. The DL1000 is the only bike I've kept over many years of riding, I'll probably never sell it, part it out maybe someday or take it to the scrap yard!
