Have an 05 ultra with a 103 installed by h.d. when the previous owner bought it new. He crashed it last year then sold it to me with the p.c.111 installed along with s.e. air filter and v&h exhaust. I took the p.c.111 off. gas mileage was only 25 mpg. I have no c.d. disc for the p.c. can it be programmed for better mileage, or do I go with a s.e.r.t. that the dealer wants to install. Thanks for any help.
