Bud, go against the tide. My L99 was the same way until I got rid of that crappy 2011 L99 exhaust. 2.3/4 BBK mid x pipe and Magnaflow street axlebacks. Then I could roll at 5 mph and just press the throttle a bit more firmly and the tires would spin for like 2 car lengths. My 2012 LS3 stock axleback seems like it is straight through, I don't recall my L99 being straight through. Oh and after say like 15000 miles things change trust me. Seems like these engines need a lot of break in for the real power to come into play.

I picked up my L99 vert last summer and experienced some of the same issues ... sluggish power and inability to do a burnout or even squall the tires a bit. Part of the issue is that the vert is heavier than the coupe (by about 300 lbs). Also, the type and especially the size of tires keep grip on road surfaces QUITE well and make it difficult to spin em up for a burnout or even to slightly squall the tires.

It took about 3-4000 miles for my car to really waken up. I did a fuse pull earlier to see if it would help, but it didn't seem to do much, if anything. After it started to wake up, I found that it surprised me a couple times by trying to shift out from under me under aggressive turns from a stop.

As the tires have worn, it tends to break loose a bit more frequently (and inadvertantly) ... especially so when the temp dropped through winter as the tires do NOT grip as well below 45 degrees or so. I think I scared the hell out of my salesman when I took him for a ride topdown and entered the roadway at the dealership fairly aggressively. The temp had dropped to upper 40's and even with nannies on, the backend broke loose shifting about 30 degrees out of line further than intended. I backed off throttle as Stabilitrak started to kick in and was immediately squared away and ripping up the road ... must say it gave us both a rush, albeit an unepected one.

Even now, with 14k+ miles on the tires, to do a burnout requires a brakestand, though it does so reasonably easily (if and only if ya turn TC off)

And Convert-11, your orignal post stating that pressing the button twice "activated" Stabilitrak was what led me to explain each of the settings (since pressing the button twice actually deactivates). Wanted to make sure that you knew what each setting was and how to get it setup the way you were expecting ... sorry if I misunderstood ya!

i felt the same way about my 11 vert. At 7000 miles i switched out my k&n typhoon for a vararam and got a tune. I walked out with a whole different car! My car has no trouble breaking loose now and is how i expected it to be when I got it broken in!!!

You're taking it to a dealer and complaining about something you imagine your car should be able to do. But there isn't any hard evidence that anything's wrong. You really need to dyno your car so you at least have some point of reference, even though comparing to someone else's dyno results aren't really that accurate either. It's still better than having a tech try to troubleshoot something your gut says should happen.

This isn't a Corvette, even the Vette convertible weighs a good 900 pounds less than this car. Plus you have a few other things that aren't exactly in your favor (slightly down on power because of the L99, torque converter for a little more driveline loss, etc.). Plus, plus your whole argument has been revolving around the fact that you're unable to defeat something that the tire designers specifically engineered into the tires, namely to grip the road.

Seriously, you might actually have something wrong, but unless you bring something to the tech that supports your claim, it's all just conjecture. If you can prove that the car's messed up, you might be able to get them to reimburse the cost of your dyno run.

Thank you all for your responses and feedback!!!

Great conversation!

If you can get her to a dyno and have it tested. You should put down 320-335 HP. There is a thread on here somewhere with L99 Dyno runs. 98 degress outside and my car put down 336.

You have to look closer on page 9-41 in manual; in middle of page the last sentence says: If StabiliTrak needs to be turned off, press and hold the TCS/StabiliTrak button until the Traction Control Off light and the StabiliTrak Off light come on in the instrument panel cluster.

You hit the button twice in rapid succession to active Competitive Mode which allows for a more sporty response from the vehicle and is for use on road courses and not public roads. This mode also allows for Launch Control on manual SS Camaros. As for holding the button down for the 7 seconds as mentioned the manual says nothing. I hope this helps to answer your question.

Jeff, I was hoping you would jump in as the reason I am asking goes back to a post I submitted last year about power issues. I have tried my car with the traction control off and both the traction control and stabilatrac on (both lights on) to get the car to light up the tires, but it won’t. I can’t even get it to break loose around a corner. I’ve had the car into the dealer on several occasions, but no trouble signals so I’m told everything is fine. I’ve done the fuse pull, swapped out the MAF, etc. everything else I’ve read in posts. I can’t believe that a car rated at 400 hp or around 330 hp at the wheels (have an automatic) can’t break the tires loose from a stand still or even around a corner. I’m considering putting the car on a dyno just to see how much hp it really makes. Maybe I’m just expecting to much, but I don’t think so. Do you have any other suggestions?

Going to vent a little more. I’m currently renting a Maxima and this car pulls until I let off the gas. Sad to say that I have a bigger grin driving this sedan than my muscle car!

I'm gonna ask the obvious question since no one else has. You are using 93 octane gas, right? My car really woke up a after I installed the OTR intake and a fuse pull.

Jeff is no longer on the website. Is there a question that you have for us? Please let me know.

my 11 vert just barely breaks loose on takeoff with traction control of and on turns I can get it to fishtail. I think pulls very strong I have a halltec cai and a solo axelback I put them on within the first month I bought the car so I dont remeber it stock. i got 20000 plus miles and Im fairly happy with it. saving for an slp supercharger tho. Cause horsepower is like money you never have enough

Fuse number for stabilitrak?
