I think I figured out part of my problem, as soon as someone said peddals not going 100% I checked mine.
They flicker, so I get 100% at random intervals and they constantly change between 70-90%.
My wheel also sometimes spazes, but I've learned to deal with that.
My wheel is a cheap Nexxtech $14 POS. so I'm realy learning why it's so important to have good gear, setups mean nothing if you can't controll the car properly.
