Default A8 tuning

Does anyone have any experience with having their a8 tuned. I see COW offers tuning, but the details of it are not real clear. I am looking for someone who has firsthand experience, preferably with a stock or lightly modified stingray. What kind of changes are made? What are the benefits? How does the car feel after tuning?

I have not had Z06 A8 tuned yet but I did buy an unlocked TCM form HP Tuners and installed it. Just need to get to the tuners to have it tuned. The new unlocked TCM form HP Tuners comes with a stock tune so you can install it and dive fine until tuned.

I had mine tune and all I see is that the torque converter lockup was disabled for gears 1-5. I guess locking those is just for fuel mileage. There is also no fish bite or shutter in the unlocked gears now.

Chuck Cow tuned my Supercharged Stingray. His A8 transmission tunes are very aggressive. It holds gears longer and shifts quicker and harder. I’m actually going to see him at his shop tomorrow eve. I need a slight tune update being I hollowed out the cats and I’m now getting a code. He can be hard to contact, you’re actually better off calling him evenings.
