Std bhp is 250, so it's either tweeked or he don't know what it is

RS4 (same model) makes a huge 380bhp tho, and the only main differences are the turbo's, intercoolers, ECU and exhaust, the rest of the engine is pretty much stock, so you know there is shit loads more to come! 500+ bhp from one of these is not hard to come by!
