Are you running the stock radio? I did not think the stock radio had EPA. Correct me if I am wrong as I do not do RTR.
The RTR radio "TF-3" has this dial thingy called the "Steering Dual Rate", which kinda mimics the way EPA works. You could adjust your steering servo end-points to some degree using that. Its on page 9 of the Savage X RTR manual.
