The new Yale is the same as the new Hyster units. The issue you are having is they have the setup wrong on the truck , have the yale dealer come out and reset it to your liking , the travel can be set to stop quickly, or give you a long coast pattern ,it is all in the setup of the computer controls , if they are not willing to do it , the hyster dealership there can also do that for you , as to the power issue the new unit more then likely has the mazda vs the old units with GM.power...if the dealer works with you there is no reason he can not make the new unit perform to your liking.
