BITCH, PLEASEbut little empirical testing has been done.
Bob posited that the purpose of the spring was to increase the speed which the valve opens, increasing performance. I would guess that this is what the Larami engineers had in mind, but I doubt they put as much thought into it as we give them credit for. In reality it does not seem to affect average power, but does make the power somewhat more consistent. I personally do a pen mod, since I prefer the feel of a trigger without a spring (at the sacrifice of some accuracy).

You did it with a plugged pump remember. Bob was super mad about that since the factory design was for the stock pressure.

True, it might actually do something practical at stock pressures.You did it with a plugged pump remember. Bob was super mad about that since the factory design was for the stock pressure.
But we don't really care about stock pressure.
MOAR POWEREEERRRRRR

I think what he's trying to say is the actual TRIGGER spring was taken off, the one that pushes the trigger, not the one attached to the tank.
I think so too and if that is so, I did that to my air tech 2000 quite a while ago, but with paint it occasionally wouldn't go all the way forward thus not holding pressure.

Anywho, judging from Daniel's observations, it is a matter of preference. From my experience and with my absolver 4B, I have realized that a regular trigger pull yields considerably weaker distances than a very fast and strong trigger pull. Given this, I prefer a trigger pull that is sudden, and not eased into (purpose of that spring). Just do what you like best as it appears that the presence or absence of a trigger spring does not affect the power by much.

Anyone find it ironic that the mods turned this into a discussion thread?

The purpose of the spring is to do exactly the opposite of what you described. It is meant to deliver fast and consistent trigger pulls, since for force less than the force required to open the valve, the spring compresses and stores the work done by your finger. The end result is more power deliver at time of valve opening than what you would get without the spring.
In the argument of fast strong trigger pulls, keeping the spring is better, assuming that the spring does not hit solid length before the required force to open the valve (as determined by the pressure in the tank and valve surface area).
Whether "regular trigger pull yields considerably weaker distances than a very fast and strong trigger pull" is a statistically significant fact is questionable. Also so is whether anyone really cares given that most people do the pin spring mod out of comfort reasons and only justify it with range reasons (presumably for the sake of earning more internet points).

This is all correct. A practical summary:
The spring provides a small performance benefit at the pressures we use these blasters at. Removing the spring may confer some ergonomic benefits that are worth sacrificing that small bit of performance.

Super Soaker Max-D 2000 (I don't know if others in the same line have it)
It's hard to see, but there's a cam-like action going. Once the trigger rotates the triangular piece to a certain point, a spring will snap from one position to the other (like an toggle- style 'clicky' wall-mouned light switch.) This opens the ball valve very quickly.
Images thanks to sscentral.org. In fact, they have a good explanation on how these work, as well.

SuperMaxx 1000 (photo courtesy of CheezyPizza)
The < shaped piece holds the pin valve shut while the trigger compresses the spring around the pin. When the trigger moves to the 'break' point, it rotates the < piece down, and the pin valve pin is free to move.

Plunger Rod Valve
The NF plunger bar primed allows the pin valve to close. When it is fired (fully forward) it pulls the pin valve open. However, the reservoir is pointed backwards relative to the NF.
