For your first question advanceing your timeing will make your car fire faster and thus burning more of the fuel and producing a little more horsepower and a little better reaction time. Second question I am not sure what your talking about a 2 step. Third question a turbo timer allows your turbo to cool down by metting the motor run for 30 seconds at idle thus keeping your turbo bearing and oil passages in good shape so if you dont have a turbo then you dont need one. Next cam bears allow you to adjust the cam timeing to speed up your valve train timeing also you can slow it down, Horsepower from these can be gained and lost depending on how you adjust them. The best way to use them is to take your car somewhere with a dyno and adjusting them there.
