Whats your in game name?
As for tips, record your fights ( i record only the fights not the fly to or crash parts) Then play back the films. Check to see what range your shooting at (right column) you can slow the play back down to see better. Then adjust your convergence for that range unless its something over 500-600, your just wasting bullets at that point. 200-400 is the sweet spot, the lower number for cannons.
Dont hold down the trigger. try to fire in bursts. Pull your lead, easy off the stick and fire, reacquire whats left
The rest is pretty much just practice. I like to go into an off line arena, turn on the lead computing site and make runs at the drones ONLY firing when the pipper and green cross hair match giving me hits. On play back the film wont show the green cross hairs but if you only fire when on target you can see the lead you need to get hits. Try a bunch of angles so that you can see different leads.
