I have that tuner on my 1200Low, i think its worth it regardless of just stage 1 or if your doing extensive motor work. Right now i have the Screamin Eagle A/C and the Vance and Hines slip-ons with the tuner, (I live in denver) I dynoed it at 78hp and 78 ft/lbs. Next winter i have a lot of plans for my motor so the tuner will come in handy. Turn the ignition key to the 'On' position, but don't start the bike. Click the 'Get ECM' button on your screen. This will give the Screamin' Eagle program your bike's VIN number, file information and computer ID number. The race tuners are 'locked' tied to each bike individually. You should have been given a little interface with your instructions and disc. Its about and inch or so wide and a couple of inches long. You need this to access your tuner.
