It's been posted here multiple times that kits shouldn't be made with less water then recommended in the instructions. For example, making a 23l kit with 19l of water. It's said that the resulting wine will not be balanced.
However, I tasted more than one kit (almost always a red) made with 23l of water that seemed "thin". I'm wondering if anyone has actually tested a finished kit to see if it is fully balanced.
The kits are designed to have the right acidity among other things. If you reduce the water, they will probably come out too acid, maybe too tannic, and may have other problems. If they are thin, you might try boosting them with some bananas which can add body or even some fruit juice. But it may not come out the way you expect. (Maybe better than you expect.)
SG, I didn't quite follow all of your test. Are you saying that by breaking them down to 2.8 gal batches they were made up with less than the recommended final volume ie. 23l?
The following is from a previous post that explains how to determine this when planning each ferment. It is really quite simple and once you learn to do this you should have no further problems with sugar management. HTH
When (or if) a ferment will "end" (die off) depends on which yeast strain is used and how much sugar is in the must. It is really quite simple to determine this when planning a ferment. First, go to:

Print this if you can. Note the "Alcohol Tolerance" (AT) column. This tells you how high each type of yeast can go.
Second, Get a decent (full range) Sugar/SG chart with a PA column.
Third, (example) Take an SG reading of the must. Look at the PA column on the SG/Sugar chart for that reading.
Next, compare the PA to the AT of the yeast you have elected to use. If the PA is *less* than the AT, you will end up with a dry wine with alcohol equal to that PA. BUT - if the PA is *greater* than the AT, the ferment will "end" (die off) with alcohol equal to the AT and there will be "residual" sugar left in the wine. Just how much sugar will remain can be determined by locating the AT *number* in the PA column of the SG/Sugar chart. The *difference* between this number and the PA of the must will tell you how much sugar will remain.
Of course, there are a myriad of variables, but this method will give you very good "working" estimates for planning your ferments. This is especially important when doing "old fashioned" (residual sugar) ferments because it allows you to balance residual sugar levels against the somewhat elevated alcohol levels encountered when doing such ferments. HTH
FWIW - If you are going to do "old" recipes, you will be best served by selecting yeasts with ATs in the 13-14% range.
I happen to have several small glass carboys 2.8g ea so I mixed all the kits except one together in my primary fermentor and divided the juice out into the various glass carboys for fermentation and set the different starting SG by dilution.
I then used the original kit processed as per instructions to top these up after racking.
