Sluggish off the line
My vette doesn't have the feel like my TA did when it was stock out of the hole. The tires don't even spin in the vette at all. Anyone else like this? Just trying to see if something may be wrong. :o

I'm assuming you have a A4? Did the car ever have the power to spin them? I assume you're launching with TC off? I'd suspect the torque management part of the the software causing your reduced acceleration.
Datalogging will tell you if that's the case.
Also a trip to a dyno will confirm if you have proper hp, if you're not putting down what you should, you can start down the road of looking for mechanical and/or tuning.

Well I'm not running any converters since I have an off-road x-pipe. I did reduce my torque management with HP tuners already. The car never really felt like it wanted to spin the tires. I thought it would at least with the mods I did but it still really doesn't.

Remember, there are a ton of different places to reduce torque mgmt. There is a "maximum torque" value on a totally different table than the torque mgmt table (since the TM table is mostly for shifting). Also, your initial base timing might be real low and causing a lack of low end power.
Do some logging and see what your timing goes to when you floor it from a stop. Once we see what the motor is doing (or trying to do) we can help ya troubleshoot better. If the timing drops to single digits, you have something in the PCM trying to rob some serious hp.
