Answer
The Harley Davidson up load did nothing but richen up your fuel curve across the entire rpm range. That is NOT the way to tune a EFI, Raising compression and changing you motor size you will have to have the bike tuned correctly. There is only one true way to have that done. It is called a Power Commander USB and after it is installed the bike will have to have a custom map made for your bike.Using a Load controller dyno with a air/fuel ratio montor,,  No down load map will work correctly. Also get rid of the S.E pipes and install a set of Cycle Shack PHD series 2" stepped headers and gain 10 to 12 more horse power and torque in the entire rpm range of your motor. There is no better exhaust system on the market today. Johnny
