Default .48/55 vs .48/60 T3 on a RST..

Having a new turbo built up (stage 3 you might say) and was considering going 60 trim on the compressor wheel instead of 55, previously running a 50 trim.
How will this effect the turbo's response/performance and will the turbine housing/wheel become restrictive at all? Obviously it will mean more lb/min of flow in at any given turbo RPM but what other benefits/draw backs are there?

I'm on stock manifolds but with a NMS ported head (stock valve sizes), the off the shelf Newman RST cam and slightly higher than stock CR, still a 1600cc.

All thoughts and input welcome!

Compressor maps...





Can't seem to find a 55 trim comp map yet....

Cam spec...
