Im also getting really low effieciency (like 800 balls on a 68/45 fill) and its just doesnt seem as smooth as some of the others ive shot...
As to not troubleshoot individual o-rings, replace your valve and powertube o-rings and see if that helps. Your experiencing more kick because you have the pressure higher than it's supposed to be, likely because you have a leaking o-ring and as a result need higher pressure to achieve the proper FPS.
As the others have stated, the only way to adjust your pressure on the GT is by adjusting the reg/hpr. Should be around 100 give or take.
