I have a 2015 Audi S3 with Unitronic stage 2 software and stage 2 DSG tune. Since the tune I have been getting wheelspin on launch control through the first 3 gears!! Traction control is triggered if I floor it in any of the lower gears right through third gear.
The tires are brand new Michelin Pilot sport 2 summers. Could the tires be the cause?

Sounds like your haldex pump is dead

I have APR stage 2 and APR TCU tune as well. No wheel spin for me. All traction! But I just don't use launch control. Obviously disabling traction control to use launch control could have an affect. Might be the system is momentarily overpowered with the additional power and torque on super fast launches.

Pilot Sport 2 are an old design - check the construction date that will be stamped on the sidewall. They may be NOS, and if 5 years or older, are now hockey pucks.

But I think s3burgh is on the money - sounds like all the torque is going to the front.

Just the fronts or all 4?
When haldex dies,you roast the front and go nowhere.
There is a TSB for the pump - common issue.
