Rot, first rule when being chased by a turn and burn A/C with a Alt and E "situation advantage" is NEVER dive, never ever dive.
Most planes can keep up untill level alt is reached then they bleed off fairly quick, in your jugg you would have been better off applying a +1 climb with a slight rolling turn, the second you see the enemy cons icon range falling away level out and fly off.
And if you do, say your being gunned at from 1k or closer and closing, put the plane in a slight* -1 dive with a gentle turn. It will keep your speed and make a gun solution much harder.
Keep in mind this wont work with 44-45 birds,as they will have just as much dive and climb power as any.
