The .63AR on the hotside will make that turbo efficient right up to 500whp. A good friend of mine, and retired Mod Fiznat made 420 to the wheels at 20 psi with no cams or anything. Just boost and a tune he did himself with the AEM EMS. Personally, unless you need more then 400whp, I'd go with the .48AR for less lag.
