There's probably a million different things you could try, but here's my two cents:
Switch to 4-3-3 with emphasis on attacking. Put 3 competent strikers up front. Keep passing set to normal. No playmaker.
With FGR, I usually score more goals than any other team in the league. Some seasons, though, I allow more than all the other teams, too
In my current campaign, I got promoted to League 2 in season 1, then relegated back at the end of season 2, then 3rd place in season 3. Did not win the promotion playoffs, unfortunately.
Scored a ton of goals in all 3 seasons.
