Tune ecu cloning

Evening all
Could someone pls tell me if its OK to load another Rocket onto my existing tune ecu or would it need to be setup separately

You COULD load someone else's tune if they have the same type of ECU. Different years and trims may not be compatible. The tune I have on my 2008 was originally created for a 2006. However, even if that tune is optimal for their bike, it may not be optimal for your bike. Unless you find a tune for the same exhaust and air intake you have (I did), I would suggest taking it to a dyno tuner.
