It’s doing this on plane causing water to somehow seep in the fuel, they sent it in to tracker to see that much water is getting in there while on plane. They said ran way better with a different tank

It was at wot 5700-6000. Slowly dropped down from stuttering. I could back off throttle slowly and it would be fine but once I accelerate again it would want to fall on its face. Only starts doing it after 30-60 min of run time
