PERON IC is the new kid on the block and is the best around (by all accounts) and that's a straight swap for your standard one. With that on board plus a HPFP you'll see around 360-375bhp and a min of 360ft lb. Add a Audi FPRV along with the HPFP, cheap little mod but needed.
If manual, you'll need a uprated clutch too.
