Pros are it flows enough to support 650hp, and it'll spool fast.
Cons are it'll be really hot. This is because the s300 frame turbos aren't big enough to effectively cool the fire (remember you have a lot of cubic inches which makes spooling turbos much easier. Also makes more heat) most people who go the s300 route don't feel comfortable putting anything more than stock fuel (sometimes not even beyond a tow tune) because of egt's
S400 frame turbos do much better on the 6.7's due to their larger housings, turbine wheels, and if my logic is sound compressor exducers
