Default 2012 LS3 Power Question

I have been a Vette owner for years now, 2 C4's, a C5, and now my C6 which I have had for just over a year which I have really just started playing with.

Does the C6 have some kind of "nanny mode" or something??

I have a 2012 C6 coupe with A6 paddle, and when just driving, it seems fine, I have hit the go pedal doing 70 and it will still throw me back in my seat every time, but from a stand still the car is basically a slug.

It does not matter if I have it in D or S, if I have TC/AH on, off, competitive, or any setting it will bark tires, but won't spin them and wont break loose the rear end.

I have done some playing with it over the past couple weeks, and if I try to do a burnout/power brake, or even just rev it, the engine it seems to bog down on me.

Anyone else experience this? My next step is taking to the dealer to have a diagnostic run on it, then a tuner, but anyone have any insight on what could be wrong before I go this route?

I have a 2012 A6 also and with traction control it acts like you say yours does. With traction control turned off it will spin the tires really hard from a dead stop. If I try a burnout it will spin the tires until you get tired of spinning them.

Even with TC off it wont spin the tires, it will bark them, but not spin them. When I try for a burn out, it still bogs down and says "NO SOUP FOR YOU"

I want some of those tires.

Realistically though, I'd guess there is a malfunction in the TC button. Does the little car fishtailing show up on the dash when you press the button?
Another thing to check would be to see if there is any device plugged into the OBDII port. Also check for any extra wires coming from above the skinny pedal that don't go into an OEM type wiring harness. (aka Vitesse controller)

I know, right....I wish when I was racing my C5 my tires would of grabbed like that.


I already checked out Mr Squiggly, and he shows up when I turn things off...and when I do things to make the rear wanna slide a little, so that is working. I didn't think about looking into my OBD port to see if anything is there.
