Bit much. More calories may result in more weight gain but at a point it’s just more fat gain as a percentage of total gains. Probably better off with 10-15% more than maintenance
1g-1.5g protein/Lb of body weight. There’s no hard limit but no advantage to exceeding these levels if already in a surplus. Perhaps if you are exceeding these levels you’re not getting enough of other macros.
Fats is a bit contentious. Some people go 0.3g / Lb, 20% of calories or some people use a set number.
Fill in the rest of your macros with carbs. Yummy and provide training fuel.
So unless there’s been significant changes in bodyweight up carbs mostly.
