The problem with sprint

For some reason, the sprint is very unstable. I don't have this problem with the Y6 or YK2 on my controller, but if I lean even a little bit off-axis, I break the sprint and do a weird jog that goes into a sprint, back and forth. I've reduced my dead zones and check on another monitor with an emu controller to check my inputs and my L3/R3s don't move one iota.

If it helps, I'm using a 360 controller. Like I said, I didn't have these issues in YK2 or Y6. Is there a way to switch to holding the sprint button instead of pressing? Maybe this will help, I don't know. But it's really annoying when I try to jump over a wall and just clumsily run into it to get hit on some dude's shin. And generally just move too.
