SHOULD I BE MORE CONCERNED THAN I AM?

...they have "Jacked" with the software to raise the power level up on 11m past 100w PEP...someone raising the output on 11m(or even other bands possibly) to past 100W PEP(as they can produce more)...

Well Dayum! ,................. perhaps it really was splattering down to 15 meters

Mine certainly does, and works rather well with most coax feed antennas around 2:1< (maybe more ) range.
I will caution on this...If the radio was modded before you purchased it and they have "Jacked" with the software to raise the power level up on 11m past 100w PEP...the antenna tuner may already be damaged. I seen several for sale..."antenna tuner needs alignment"....RED FLAG! dead give away for someone raising the output on 11m(or even other bands possibly) to past 100W PEP(as they can produce more) and BURNED the tuner up using it on 100W+ of carrier (AM/FM/CW)
Factory Replacements are now Out of stock at Yaesu (I believe) and if you can find one prepare to spend up to $300 to find a new one! (GL)...not to mention having it installed and radio returned to factory specs.

Doesn't the 950 have an inbuilt ant tuner?

Yes it does.
