if i where you i would run very fast from that shop. you should gain anywhere from 20 to 50 rwhp with a tune

what about my issues with torque management, is it really causing me to have issues from a dead stop acceleration?

From my understanding there isn't as much torque mgmt on the LS3 like there is on the L99. A good tuner should take some of the torque mgmt out.

Are you turning off both TC and Stabiltrac? When I do that, roll about 3 mph, rev it up some and dump the clutch it should get sideways on you. Mine did that stock. Just be carefull if you try that.

Also, I noticed your tires are sticking out a little in the rear. What wheel size/tire size did you put on back? It's possible that your combo is a larger diameter size than stock. If so then you might have upped your effective gear ratio. That's not a good thing for these heavy cars. We need all the gear we can get.

i have TC and Stabilitrac both turned off, i just though i should be able to light them up from a dead stop without having to drop the clutch at a higher RPM than normal.

the rear wheels are 10", it was the only size for those wheels available, my tires are the stock ones.

Just curious, how many miles do you have on your 2012? My 2011 was fast at 4000 miles, but woke up even more around 8000 miles.

7000 miles

[Overkillphil]

Yeah, it should be good and broken in by now.

Do you have a manual or automatic (dead stop)?

Revving the engine & dumping the clutch (LS3) will smoke the tires.....

[Overkillphil]

Find a nice quiet deserted "private" stretch of road, hold down the TC button for more than 7 seconds, hold the throttle to the floor, and side step the clutch. Keep it mashed, and enjoy the ride as it lays tracks through second

LS3, i have tried once to dump the clutch aroud 2.5k RPM but i got a lot of traction and wheel hop then it hooked up... I was afraid to try a 3.5k or higher RPM clutch drop...

[Overkillphil]

2500 is too low in the torque curve, that's where your wheel hop is coming from. Trust me, I was a little scared the first time I did mine, but if you fully mash it and dump the clutch above 5000rpm, your tires won't stand a chance, and you'll leave mega long smooth tracks.

Even a launch control start is at a much higher rpm

[eric0353]

cant that be bad for the clutch and transmission?! 5k RPM clutch drop?!

[Overkillphil]

Proof

[Overkillphil]

Honestly that high of a clutch drop is easier on your drivetrain because the traction is completely overcome offering very little shock to the trans instead of a 3000 rpm launch where it hooks causing a huge shock to the drivetrain.
