So, I just got two Guppy Tails in the original game, on the same run, in the same room.

lol. Does this mean my chances of finding chests are doubled on top of being doubled?

No , Multipliers dont stack , I tried giving myself bunches of sacred hearts , No plus damage. Same by giving bunch of Magic mush , Max heads , And pretty much any multiplier/doubler.

Yeah I tried messing around with the mod too, seeing if I can stack items. It never worked, and it never showed as double in my inventory. But both Tails show in my inventory.

Regardless if it works or not, I think its funny how that came to be.

A thing you can do (If you have remix mod) Is giving yourself a bunch of Odd shroom small , 2 Tammy's tails , And cancer , You will be shooting like a machinegun , If you combine that with any other tammy item for turn into tammy , You will shoot even more.
Now for normal things , I remember that Mom's contact's + Mom's knife is pretty deadly.
And yeah , Pretty funny fact some items can appear more than once (The tails AND Blood bag appear more than once)

It's possible that all item effects are enabled by boolean (either on or off) so there'd be no way to magnify that if it's either true or false.
If anyone knows how the inner code of the game works and can confirm/debunk this that'd be great.
