When holding the brakes, my rev limit is restricted. Is there a way to remove the restriction?

? Check grounds.

Let off of the brake?
Does it do this on the stand if you just hold the front brake? How exactly is this happening?

It's not going to rev like a car or bike in neutral. It will try and engage the rear wheel and a stock scoot won't have the power to overcome the brake or grip of the tire unless it's on a slick surface.

When I have my scoot on the tri stand, no brake lever held, I can rev full throttle and tire flies, scoot is sliding around, but as soon as I hit either brake lever, it revs down. Is there any way to make it not rev down, trying to get my back tire to spin at a stand still!!

The rear brake would drop rpm but the front should have no effect. Sounds electrical as mentioned above. Not my specialty at all.

The rear brake would stop the wheel or slow it so that would be normal. If the front brake alone slows or stops the wheel or changes how the engine acts you either have some new anti-burnout system or an electrical issue.
Does it sputter or any other unusual symptom other than just tire speed decreasing?

It doesnt sputter or anything, I rev to full throttle, it maxes its rpms, and then pull the brake lever, it cuts the rpms, roughly in half!!

This is a new one to me. I've seen where pulling a brake lever drops RPM at idle from a weak batt or charging system or just too low of an idle, but none of that should apply at high revs especially since the Zip AFAIK should be an AC CDI.
The front brake lever should perform two functions. First it should apply hydraulic or cable pressure to the front brake itself. That should have no bearing on what the rear wheel or engine does whatsoever. Second, it should complete a circuit that allows the brake light to illuminate and potential e-start operation. That should normally never have any effect on engine operation other than power demands at idle as previously mentioned.
If you have a multimeter you could check to see if any wires from the brake lever and kill switch have continuity with the brake engaged or not. Also make sure nothing else strange is happening, like lights coming on or off with the brake (other than the tail light).

Ok I played around with it a bit today, holding the front brake does not restrict the rev limit, I thought it did but I was wrong, what are some upgrades I can do to get my back tire to spin at a staand-still? I can hold the front back as tight as itll go and it just slides in place :/

There really shouldn't be a need to rev the engine high on the center stand. What are you trying to accomplish? Are you trying to do a burnout?

Put a small puddle of soapy water on the ground just where the rear wheel is, mash the front brake standing up on your feet and gas it!
Bleach is really slippery.

If it's in a decent state of tune no mods should be necessary to do a burnout. Technique helps. I hold the front brake, stand up, put pressure/weight into the front to to take weight off of the rear tire, grab a handful of throttle. Here's my stock TaoTao with an old tire on dry roads: www.youtube.com/watch?v=zsFXQXf7cTcBurnouts aren't easy on parts and of course not legal on public streets/areas so that's strictly info for track use.

@90gtvert, I do that but I just take off, sliding my front tire, maybe to much throttle at once?
