M54-> M54 = nice little upgrade
M54b25 -> M54b30 is pretty close to M50 -> S50... (unless you're talking euro version). Nonetheless, a 41-51hp increase in horsepower is not insignificant, especially when you're starting with 184. That's a 22-28% increase in power. The torque delta is similar in magnitude as well. IMO that's more than enough to be considered night and day.
