Hi, I am a first time poster and last fall I purchased purchased my first cart - a '05 Ez Go TxT, series. It is fast enough on flat surfaces but really slows down going up the one big hill in our sub-division. I have considered replacing my controller to a 400 amp Alltrax but in researching my existing controller I find it is a Curtis #25864 and is rated at 350 amps. Would I get appreciable improvement going to the Alltrax? I also have new 4ga. cables ordered and will be replacing the old cables.
