[QUOTE="Veteran, post: 2416355, member: 118038"] No I think the tuner and harmonics are not directly changed by altitude. What is changed is air density and temperature. Temp will affect burn rate, velocity and time to exit barrel Air density will affect flight velocity and your groups. So tweaking the tuner at altitude is just to compensate for these things and find the setting that gives you tightest groups again. [/QUOTE]
