Main thing you need to do is getthe car scanned and make sure there is no error codes. If tou have codes mostly likely will be 17705 this is a boost leak and beileve me its a pain to find.
If you havent got any codes id personally advise at a bare minimum you change you diverter valve for an upgraded one id advise ether a forge 007p or a forge 008.
If you wanted to be extra safe id upgrade  all your boost pipes to silicone to avoid any possible splits.

^ Before any of that, ensure it's been serviced properly to give you a good base.

I wouldn't worry about getting a new DV, I read on Nikki at Rtechs fb page that the standard one is more then capable
