Default Help, Unusual C6 A6 problem!

don't know how to explain this, but I'm really confused so I'll give it a try.

On 2nd gear when I push the pedal to WOT the car seems to up shift and downshift in a horrible way, it keeps upshifting and downshifting until I take my foot off the pedal! I'm not sure if this happens only on 2nd gear because I didn't try it on other gears, I don't want to damage anything!

And I don't know if this is related but I can't switch the AH off or even select the competitive driving mode, I can only switch the TC off. I tried to turn the car off and started it again, still I'm unable to turn the AH off or select the Competitive driving mode! This is making me nervous.

Help Anyone, I'd really appreciate any replays, I'm hopeless.

Wow that's weird, I wonder if the car is in limp mode? Is the SES light on? Have you done anything to the car (tuned etc...)?

The SES light is off, and when i scanned it for trouble codes it showed no codes at all ! What do you mean by limp mode?

The car is heavily modded but its still N/A and yes it's tuned.

Limp mode is when the computer thinks there is something wrong with the drivetrain so it reduces power available and can make the transmission act up... I would take it back to the tuner and see if they can figure out whats wrong, probably need to run a log on it.
