Torque Managment?
I want to get a tune from Race IQ, is torque managment controlled through just a ecu tune? I though tcu needed to be tuned instead. Also i know people have there preferences on who they go with on tuning there cars but want to try out Race IQ, whats people’s experience with them so far?

But yes, just about everyone seems very happy with them. Torque management is achieved by your foot. Are you meaning traction control? (ABS and other systems) Or do you mean increasing the torque limits for very high hp cars? (Yes TCU is involved) Or do you mean increasing the torque via tuning to be all it can be? (ECU tuning only).

The tcu sends a tq reduction request to the ecu. This request is a specific amount. Not just hey I am shifting. The Ecu will go to this requested tq value by several different means in order of capability. So small requests can just be timing. A large request may be timing then closing the throttle. Etc.
I do not suggest turning this off. It does not make your trans shift faster. It actually makes your trans shift slower and wear out faster. If you want to have firmer shifts then either get a tcu tune or a valve body to speed up the shifts. But still leave the tq management in place.

If I roll into throttle coming off the line it will never spin. I have tried just flooring it off the line to see what happens. Feels like power is smoothly dialed out. Hard to explain.

If you are asking if a torque limiter is preventing you from getting full power off the line or in acceleration when not shifting then the answer is no. You are just not making as much power as you would like. Throttle curve is a programmed value in the ecu as well. But the tcu is not limiting you from launching hard.

I can spin the wheels in the dry from a roll no problems. Admittedly my tires are rubbish but even before the mods it was very easy. I don't think there were any changes from 05 to 06 in terms of traction control. Spinning wheels only slows you down so if the car is pulling like a freight train....

If you drop the trans down in 1st gear from a dead stop, turn off TC, and step on it... you're going to spin, a lot.
You can leave the car in sport or comfort mode and manually drop a gear or even a few, and the trans will still shift for you. That's exactly how I roll race.
