*500cc per minute is approximately equal to 49lbs per hour which is equal to approximately 100hp.
* lbs/hour = cc per minute / 10.5
* lbs per hour = HP / 2.04
* cc per minute = lbs per hour x 10.5
* cc per minute = HP x 5
* HP = cc per minute / 5
* HP = lbs per hour x 2.04

Minimal power gains. Good for emission and idle quality. Good for odd-cylinder engines and big injectors (like Audi 5-cyl etc.) but doesn't really matter when it comes to power. Will idle smoother tough.

Running sequential on mine, it doesn't make any difference after about 3500 rpm though.

96lb/hr
full sequential
13.2 AFR at idle
652@ 1 bar
771@ 1.5 bar
My injectors are actually too big, I should use 72's or even 83's, I don't really care to have the BIG numbers. I am happy at 1 bar. My injectors are set to .25ms which is the lowest they really can be fired, if I go lower they don't fire consistantly and the idle rolls too much and runs rough. I get the car to idle at 13.2-13.5 and stays clean enough not to foul the plugs.
As Goran stated, sequential is only useful for idle, once on boost batch is fine unless you are running serious power and then stagged injectors would be desired.

What's the reason? Cooling? Flames?

There is no drawback with running sequential injection except more expensive EFI and more complicated cabling. If possible, it should be used. But it doesn't matter on the track.
