Hello Greybeard and welcome to the site.
When you say your 07 needs a tune, are you looking to remap the engine, perform some preventative maintenance like replace plugs/filters and adjust valves or is the engine running a little off and you figure a tune up is needed? We also need to know what's been done to the bike along with how many miles are on it.
There is a lot of info available in the "stickies" posted in the General Tech Talk section including balancing throttle bodies/TPS adjustments etc. The search function will also give a plethora of info. The gang is also very knowledgeable willing to answer any questions asked.
