Congrats! Maybe you can try taking on some Cayenne Turbos now!
You can't be that far behind at this point. The 4.8iS is listed at 355 hp stock with a BMW-listed 0-60 mph of 5.9 seconds. Then figure with the added CAI, exhausts, software, and throttle body, you must be somewhere in the high 380s at peak rpm, and easily shaved 0.2 sec or so off your 0-60 times.... Or to put it simply, you are now "STYLIN' AND PROFILIN'"
