Torque management
So i just wanted to clarify my vette is sluggish in 1st gear till about 4000-4500 rpms, then when shifting to second i can get a chirp. Is that the torque management coming into play?

When I first bought my 99, I thought it was real doggie in first and second under hard throttle. Felt like something was holding it back, would not break the tires loose, then turned off the TC and when under hard throttle in first and second it immediately smoked the tires !!!! (for what that is worth) The TC applies brake on spinning tire and retards the timing.

What year and mileage is on your C5? You give it a tune up yet? The only reason the C5 Z06 lights em up easy is because of the first three gears, its what makes it feel like an animal compared to a normal C5 put in some 3.90s and you can spin them at will also.

1999 110k miles. Im not trying to just spin them im just trying to get a better response in first. I am about to check spark plugs, oil is good. But like i said im surprised how fast the car is except for beginning of first.

. Also Fwiw if the engineers never changed the throttle on 1997-00 to 01-04. Then u should get more throttle response from traction control on.
Only when u go WOT and shift does torque management mess with the drivetrain. Ive found best throttle response with TC on > TC off > competitive mode.

If it's the way the earlier C5's are then it reminds me of my buddies "old" Mercedes SL500. The car actually had some oomph to it, but if it didn't hook right it was a dog. Poor traction control system IMO.
My 04Z has a much better system, better than my previous BMW's as well.

When you mash you foot to the floor,,, the THROTTLE BLADE "DOES NOT" whip open to full throttle! 
YES,, "Torque Management" only opens it at a smooth and predetermined rate.
SO,,,,, If it were me,,, and I wanted more aggressive throttle response, I would get a PCM Mail order tune.
I know Chuck COW at Corvettes Of Westchester has an outstanding Mail Order Tune and also includes a throttle response enhancement that makes the Accelerator Peddle more linear and aggressive..
Give him a call. The Mail Order tune isn't all that expensive but it makes the car a LOT MORE FUN!

I did try it with and without TC and first gear felt the same, shifting to second i felt it activate the torque management but it was after it chirped the tires and was on the gas again (guess i shift faster than the computer can think)

TRACTION CONTROL SYSTEM (TCS)
The Traction Control System (TCS) uses spark retard, throttle close-down and rear brakes to enhance vehicle
acceleration and stability. TCS is capable of functioning up to maximum vehicle speed. Traction control is
given priority at low vehicle speeds. Directional control is given priority at high vehicle speeds and during
cornering. During a cornering maneuver, difference in front wheel speeds is monitored to detect cornering.
During low vehicle acceleration, control strategy is more sensitive.
The TCS is capable of simultaneous or separate usage of engine control (spark control and throttle close-down)
and rear brake intervention. When a TCS event occurs, TCS disables cruise control and torque converter clutch
(automatic transmission equipped vehicles). Traction control logic uses a reference speed from the non-driven
front wheels. A sophisticated slip threshold calculation considers vehicle acceleration, vehicle speed, cornering
and start-up. There are rear wheel acceleration rates which will trigger rear brake intervention to reduce wheel
spin.
