I have Pilot Sport AS3+, about 20k on them. Would love to have a TCU tune but really don’t wanna spend the money right now and probably wouldn’t go Unitronic again anyway. Trying not to put anymore money in this car, currently saving up for M340i or S4 in the next couple years.OP,
What speed are your tires rated for?
Keep that in mind when you push them.
The impact on tires also depends on how long you stay at speed, age, wear, etc.
New tires best for higher speed runs.
Do lower speed testing to make sure no internal tires issues before a high speed run.
My thoughts.
Unitronic, love my tune. Sure there are better, but for a dialy fun driver it is smooth and solid.
TCU helps handle the extra HP. For those that want a smoother DSG, Unitronic helps with this.
