The Yamaha controller is programmed to operate at the legal speed of 19.7 MPH.
Any improvements changing the cart speed will put the warrantee in jeperty.

Speed and performance can be attained if you have performance gear kit installed on your cart. With the proper gear train you should not have any problem on our hills with your cart.
