Thank you. I appreciate the reply. I have an LX handset and access to the manual. I'm just not 100% sure what the settings should be for my truck.

The new controller probably needs to have the parameters adjusted with a LX handset....do a google search for GE SX controller and read the pdf document fron (FSIP) Flight sytems......www dot fsip dot biz
They offer free dowloads of most motor controller manuals
With the LX handset you can adjust the controller to your preferences....including speed, current limit and 1A operation
