On my N55 i have the vrsf DP and wow what a difference, intake i used was the burger tuning, i still have the exhaust to do, and have the tune done at turner, and yes im rolling the the engine light from the cats being removed, does not hamper performance, the charge pipe is the next on the to do list, once you source the DP theres a big difference, and dont forget the DP fix if your state has yearly inspections, BOV mmmmm thats a little tougher
Go fast bits has a improved on turbo bov that is stated to hold boost better, the most ive seen with a full fledged bov is custom turbo and intake with dedicated waste gate DP ive looked into the catch can as well and your best be is to get a universal kit, but spend the little extra cash and get quality universal kit
