K & N Panel Filter $50
Vishnu XEDE $750
TBE $600 (as you say)
Recirc DV $100 -$125

You should be good for close to 300whp with this setup and can go in for warranty work by swapping out the down pipe and removing the XEDE tune, its also eliminates the need for a MBC, this is the route I wish I went in the first place, living in CO and having changing altitudes all the time means my MBC needs to be adjusted a lot, not cool.... anyways I know my list is a bit more than $1200 but worthy checking out.

You could get your ECU flashed for pretty cheap if you attend a local flash day, a mbc is like $125, a DV is like $100-$150, you have some gauges, now you just need a filter and exhaust. I got AMS exhaust only because I knew I wasnt gonna do many mods and wanted a killer sounding exhaust

 

Warrtalon, does the IX need the Forge RS DV since it has an aluminum BOV instead of a plastic one?
