[Elecraft] [K3] Will I Lose the 120 Watt Max If I update The Software?

[Jack Brindle]

Just how much power are you running? If going from 100 to 110 makes a  
500 watt difference in the output, then you must be putting out 5000  
watts with 100 in, assuming the amplifier is linear.

Somehow I suspect this isn't the situation...

Seriously, in general amplifiers need about 50 watts input to get full  
legal output. That's about a 15dB max gain as set by the FCC rules if  
I remember correctly. If you need to put much more than that in, then  
you either have a lot of loss in the input coupling network (this is  
intentional on some designs), or the efficiency of the finals is  
really bad (old tubes?). Your strategy of getting it checked out is a  
good one.
