I have a 99 SS camaro with a 6sp and Ls1. Everything on the car is stock and it has 76,000miles. I'm having a hestitation problem, when I hit 2nd gear at WOT it hestitates and then pulls. there is also a slight hesitation at ~2,500rpm during cruise. Also I get a slight tapping sound coming from the motor. This sound occurs from 3000rpm up during WOT. Could this problem be a lifter?

I'd look at plugs/wires first. Is the SES light flashing/any misfire codes?

I would also look at the fuel filter.

Could the clutch be slipping? Mine did some what of the same think but with no noise when my clutch was bad.

that tapping could be pinging from your missfire...check out that tunup issue first as suggested by the others

Stupid question, but, are you running anything under 92 octane? The lower RPMs with a heavy load and advanced timing could be causing predetonation, tripping a knock sensor, and causing your timing to retard.
Could also possibly be a slightly clogged injector.

Do you have traction control?It would do that-even if you don't-the engine control computer will pull out timing and fuel if it determines a potentially damaging manuver is being performed.There is a technique to driving these cars to avoid this that really doesnt affect performance that much.It's all in how you do it-but I know from a dead stop if you flat floor it the computer will make the car fall on it's face and then gradually give you back control,maybe it will do this in 2nd gear also.I haven't really seen the parameters spelled out,it's not in the factory service manual cause it's too complicated.All you need to know is that you need to back off on the throttle when taking off and shifting gears- and then flooring it again- to avoid the computer interference.See if this doesn't help -that what it sounds like to me.It becomes second nature after a short while to drive like this-I do it without even thinking about it.
