There is still room for improvement with my records. I use the controller with the claw method, my thumb on B for boost, the finger next to my thumb is on A for gas ( I ended up switching the gas button to Z, this is much easier on your fingers) This way, I can still pump boost while I'm turning. Its also important that if you hit a wall, that you pump boost back to max speed ASAP to recover better. Make sure that when you are boosting, that its done in quick bursts, like pressing the button as fast as possible, but you have some wiggle room in between bursts, so you don't need to spam super fast, as it is much more efficient and maybe faster. Hold up if you are going downhill, and down if you are going uphill.
