No, the Quad MM only increases normal memory (yes, it boosts a C -> CV). On a C or CV, you must add an Extended Functions/Memory module to have the initial amount of Extended Memory (124 registers, the same as a CX comes with).

Also, yes you must have the printer plugged-in to the 41 (even if it can't print, the ROM is still visible) in order to have the printer instructions properly stored in the efficient XROM format (much smaller than the same instruction if entered without the printer present).

As Dieter noted, it doesn't seem like that could account for the large memeory difference, but I've no idea how many of those instructions there are.

I'd suggest stepping through all the code and deleting and re-entering all the print related program steps, with the printer installed, to be sure you have eliminated this part of the problem.

Edit: So, it's clear I'm the slowest of the folks trying to help here...

The i41CX+ program on my iPad has the printer built in. I do not remember if I had it turned on when I entered the program recently. I will go back and turn it on and recheck the printer commands.
