IS IS POSSIBLE TO SYNC THE THROTTLE BODIES USING TUNE ECU ?...Ive balanced carbs on previous bikes using the conventional method, but Im sure Ive read somewhere that it can be done on tuneecu. which method is the safest/best way to do it

Yes you can, its on the diagnostics page, also if you have replaced your standard airbox, you can adjust them with out removing anything!

Ask your doctor if TuneECU is right for you. Side effects include rapid heart rate, sleeplessness, increased acceleration, increased emissions, obsession with tables and graphs and constant tinkering. Unless you have a PHD or at least a Masters in mechanical engineering, you should not even download the program to your PC as it could take over your life. Make sure you advance your timing as far as possible and lean the mixture until constant detonation (increased power) gives you max performance.
