There's not much in the way of 1050 tunes on T595 - I put a couple old ones on there for the 2005-early 2007 models back a couple of years ago. The last time I looked, there was nothing for later 1050 S3s. And because TuneEdit had developed a good bit since then, newer tunes are much more developed.
If you have TuneEdit (TuneBoy), try this tune:
Clicky
It is based on the Arrow tune, but better matched to low mount GP style exhausts with SAI. It also smooths out the 2800-4200 surging. It is not perfect (customized to your bike), but should be a decent start.
I hope this helps.
