Help! I think my dive shop owner might be an idiot

I bought an Aqua-Lung ACD Legend recently. I have 4 dives on the regulator.
As an octopus, I used an older Scubapro D350 second stage. As soon as I
began each dive, within 20 feet, I noticed that I have to pull on the
Aqualung regulator to get air even if the reg adjustment is increased to
allow easiest breathing. It makes it very straining and I find I have to
breathe very heavily when using the reg.

As soon as I switch to the Scubapro reg, the breathing is fine and I notice
no pull is required.

So I take the reg to Mr. DSO and he looks at it, tests the intermediate
pressure, scoffs and says its fine. He says the regs are on the wrong side.
He says because the 1st stage is upside down, it won't work properly
underwater. See when I bought the reg and hooked up my whips, seconds etc,
it made sense that the body of the first stage should be setup downwards and
tuck into the tank valve. The manual doesn't explain this well. He said
no, the body of the first stage should stick up. Listening to him, I
switched everything around and it now looks frigging ridiculous. It also
doesn't breathe any better than before.

I'm no nube, not an expert either by any means, but this whole experience
has left me cold.
