I Tuned My EFI System!!! I took a few hours, but I've got it dialed in really well and it sounds great and runs cool without flatlining in the upper Rpms or backfiring with the intake, header, slip-on combo I've installed. I can personally say the Eagle-Research EFI-E System works really well if you soldier a high quality 250 Ohm resistor inline on the white wire. My bike pulls so well now it skips from 51-56Mph on the GPS and I'm running a 17-42 Sprocket set.
