I have a set of Bass strings on my Squire P-Bass where the thickest low E-String is a 105 gauge, as far as I can tell, the intonation is pretty well spot on, I'll post a pic so you can see where I have all the saddles positioned.
Incidentally, I have a set of Elixir Strings in 42 to 09 gauge on my Hot Rod Strat, and I have the low E-String saddle set so that it is as far back from the neck that it can go, but it still reads as being slightly sharp, my conclusion is that they positioned the bridge-routing a bit too far towards the neck than it should have been.
I'll also post a pic of where I have the string saddles positioned for the Hot Rod Strat.
Here's a pic of the bridge on my Squire P-Bass guitar, the little black mark near the number 17 indicates where the scale length measurement is for the distance between the nut and 12th fret ( I used my longest metal ruler which is 600mm in length and has scale markings in both mm and inches, I used the inches scale for the measurements in this case), the bridge is made by Gotoh:
Here's a pic of where I have the string saddles positioned on the HotRod Strat's bridge, as you can see, the saddle for the low E-String is set pretty much close to it's limit for lengthening the string, and it still reads a bit sharp:
