Speed on half pipes

Pumping works different on this game. Turn off auto pumping and try to pump when you would irl (watch some irl pumping tutorials). The skate 3 timing for pumping doesn't work anymore and the feedback (rumble and the thing on your score counter) is wrong and will tell you that you pumped correctly when you actually did it so badly you lost speed.

As a starting point, try releasing a pump after a curve has fully ended instead of during it, and try pumping as you're landing in a quarterpipe and releasing the instant your wheels hit the ground. Turn on forward to pump in assists because it can make pumping effectively more easy in some situations. For instance, forward to pump is good for a pump released right after landing into a quarterpipe because if you pump with L2/R2 you might pull the board too close and land further down which will make you lose some speed.
