You can check with a GS-911 if you are really curious. I admit to not paying much attention. If within a few bars on the low side (my 2007 has really fine bars on the display) up to less than full scale, depending on ambient temps and middle of operation, I figure all is pretty well. What value does temp add for normal operation?Does anyone know that actually running temperature of an LT? Would be great to see the "Bar" equivalent in degrees. Might anyone have checked this? i.e. what would the temp be at half way up etc?
