Phase through a wall/more air on jumps
In europe, at the snowy area with the two tunnels right next to eachother that are right after the twin bridges, before the tunnel starts there is a divider in between them, (there are like 2 of these spots I think and I don't know which one it is if not both).
Don't be affraid to hit it becase should pass right through it, my friend said that he and his cousin were playing and his cousin went strait into it and just kept falling ( guess he got 7.5 seconds of air occording to my friend.....
Get more air on jumps: this worcks best if you know exactly when you will hit a jump, make sure you have A LOT of boost, use boost until right when you REACH the jump, THIS IS CRUCIAL, as soon as you touch it, stop the boost, then right when your front tires are off the jump, start using boost again.
The speed you get from using boost before the jump will make you hit it fast, then the extra push from the boost after the jump will push you a little further through the air).
