Since I got my new 2011 limited this spring, I have been reading all the post here and doing as much research as I can. After a 700 mile ride last week and frying my right leg I have decided to do the upgrade asap. Was wondering if my plan will be a good choice for the upgrade. I have a used 2010 head pipe that I am cutting out the cat, so I can keep my original pipe. Planning on the 4" jackpots. As far as tuners, my choices was between PCV or TFI, I think the TFI would do all I need since I have no plans for any more engine mods. Just want a cooler and little better running motor. Price is not a big decision factor for me but TFI is cheaper, and don't want any dyno tuning. Of course will go with a SE or similar air cleaner. Was interested in any opinions or mistakes I may be making on this set up.
