Running say a GT2860 would help because its max output is around 350 so you won't be running it out of breath. The confusion comes in that I talked to the company that makes the kit with a GT2860 and GT3071 and they said since the low-end spool is basically the same, but the 3071 can handle more power, you get better thermal efficiency out of it, and reduce engine temps, they usually recomend going from a to c and skip b.
The nutty part about the EFR turbos is their spool. Spool of a gt2554, power potential of a 3071. It's exactly what I need, and should spool 700-1000rpm qicker than the GT2860

Are you 6spd? Cause from the little research I've done the 5spd trans's start to blow apart at like 250-275
