-Musti range is same as default OOB, this is also true to other weapons, such as APILAS, KES, etc. etc. not to "break" the game's "inbuilt balance" (french Apilas has same range as Finnish etc.)
-I have given the +2/+1 not to all operational units, but only readiness brigade units. Jaeger Brigades (90/91) are also operational units, as were the armoured brigades. I gave it only because readiness brigades have a lot higher amount of professional soldiers and also the troops are the youngest (=less time from conscript training period) and ought to be (knocking wood) most important troops in future refresher training
-I may tone down the sissi's bonuses to match recce, not the other way round... If I change something.
-Coastal Jaegers say they are an elite because they do something that no one else does, speak Swedish

I really don't see a reason to promote them, maybe in modern times give them +2/+1 as they seem to adapt to similar system as the readiness brigades when it comes to troops' age and number of professionals...
-Arty bonuses came with the game, propably to represent the well known Finnish Artillery accuracy/firing method training (that has to do with the whole artillery system) - my OOB also brings the quite unique FO system to the game, at least in some sence...
-SFJ's, heard of them, seen them in action too... I think they go well under both sissi and spec jaeger, but do not deserve units of their own, as their organization is not public. They're same sort of special unit as Special Jaeger Battalion (except spec jaegers are NOT conscripts, like paras, divers and SFJ's), but instead of jumping out of perfectly fine planes and choppers, they may do more long range recce -oriented stuff?
-Don't hold your breath mate, next version may take a while. I am currently very busy with real life stuff and also (when I got time) trying to experiment with "realistic-radio-numbers" (tm) for the OOB and see how the game reacts to that. If you want to be of help, please do browse through the text files in the latest version and fix errors and typos, which are plenty

, or give your e-mail address to me and playtest the current version I have now. That version has most of the stuff OOB-wise done (plus currently has the radio test going), but I have yet to test it and finish all the other stuff (texts etc.).
