Well, I know when I have had this problem with my old hop up a few years ago, I increased bb weight. When I was using lighter bbs, they would curve left, thus causing a decrease in accuracy. My question is, what bbs are you using. If they are too light, its possible that could be your problem.
In other words, no matter how much I increased/decreased the hop up they would go left. Thats because I was using low weight bbs. Hope this makes sense. Once I increased the weight to my trusty .4s, I was good to go.
