Thank You, I look forward to it.

If you hate Deceleration Popping, Read This.

I have a 2011 LS3 with a CAI intake and Corsa catback exhaust. Personally, I hate the deceleration popping cause by the Deceleration Fuel Cutoff settings in the computer. In my personal opinion it makes the car sound more like a Harley motorcycle or an old car that is a desperate need of a tune up. Don’t misunderstand, I love a deep powerful sound and a bit of a deep burble when decelerating, not a popping, backfiring type of sound.

I discussed this with my local dealer service manager and he looked into it with GM. He learned that GM is aware of the issues and has received a few complaints from people who upgraded their exhaust. He said GM may consider looking into a solution but no commitment on timing.

I know that a custom tune solves this problem, but I am not ready to sacrifice my powertrain warranty. I would like GM to make adjustments in their tune.

So … if you hate this as much as do, I suggest that you ask your service manager to also check with GM and raise a concern. The more of us who raise the issue, the more chance GM will adjust the computer settings to fix this and we can maintain our powertrain warranty.

Please use this thread to post other ideas on getting our concern to GM including GM phone numbers, email address, etc. and any headway you made on resolving the issue.

The ZL1 pops. It's publicly a part of the car that is appealing to many.

blackjackcamaro · 07-09-2011, 01:30 PM

I like the pop personally too...

HIOFECR · 07-09-2011, 01:34 PM

Really? I didn't do it at all during break in (under load as described here) but I do it all the time now and love the way it sounds. Where did you learn/read that engine braking is bad for a motor that is broken in?

PQ · 07-09-2011, 01:44 PM

Honestly, I think you may have a hard time with this. At least here on an enthusiast forum.

I could see this making an impact on a Lexus, Infnity, Accura forum but on here we love that sound. Some of us pay to GET that sound. Mine FINALLY did it after the cam went in.

Oiy was stoked brah.........

I have a Flowmaster American Thunder cat back system on the way.

its really not "too" loud.

actualy for me its not quite loud enough yet LOL

but a muffler delete makes this car at least sound how it should have come from the factory.

and as for the decel pops.......its music to my ears

I would drive my car off a cliff if I didn't have that sound.

You do know that this will decrease your fuel mileage right? I deal with gm alot and a tune change requires a lot of emissions compliance testing. It takes them quite a long time to get the cal. Updates to dealers. Just sayin.

heres a vid of my muffler delete,

this vid actualy does the sound justice i think,
