Bully Dog was purchased by SCT earlier this year, but I wouldn't expect SCT's tuning or support by SCT Custom Tuning Dealers for the Bully Dog hardware anytime soon. Your best bet is a mild tow tune (40-60hp) for longevity from a reputable custom tuning vendor.
You can pretty much do whatever you like post turbo and be ok. I strongly recommend keeping the catalytic converter and other emissions systems functional though. The cat won't pose a restriction on power if you throw some heat at it regularly, meaning get on the throttle and hold it there up a long on ramp or up a hill. The same is actually good for the VGT turbo also. Check the health of your EGR and oil coolers by monitoring oil and coolant temps, lots of documentation on that with a little searching here. Final thing, don't mess with the air intake system. The stock filters are beyond excellent, needing only to be changed when you see an actual measurement of restriction on the filter minder. Stock filters seem to run anywhere from 50k to 150k miles depending on where you are before needing replacement, only use Ford Motorcraft or Donaldson filters, which are what came from the factory, cheaper filters will not last as long or filter any better, and there is no performance to be had from additional flow.
