No Burbles
Have a tune through Eurocharged and I hear absolutely zero burbles throughout the entire RPM range. Windows down and tried listening for it but there was nothing. Any suggestions? I feel like the dude in this video lol:

I just got a tune as well that doesn’t feel perfect for the car and perhaps waiting on codes. (Between 3-4k rpm when it would boost on stock tune the fuel cuts out like the computer is holding it back.)
my car does actually burble tho even tho I wasn't expecting it too (maybe I got your burbles).
I deleted the mid resonators and the tune def made it burble. Maybe not like a jaguar but when slowing down even on stock tune it still burbles now.

If I gun my car while it is in Sport+, then let off the gas, it will make those popping and crackling sounds as the revs drop into the 4,000 - 5,000 RPM range. I assume that is the burbling sound you are talking about?
My guess is the gas mixture is too rich, leaving gas to be ignited after the piston stroke which results in the popping sound.
Interesting gimmick, but gets old quick.

I have the mufflers on and I get the pops with regular Stage 2 tune and I asked for a file with burble tune and that file completely got rid of the pops. It was weird. Jerry re-did the burble tune for the 2nd time, still nothing. No pops on burble tune. So I switched back to the original Stage 2 file and the pops are back. I get the pops on revs and pretty much all the way down to 2k RPM. I haven't tested them from the redline, but they usually come alive between 2k to 5k rpm. Upgrading the AMG muffs probably won't change much besides the exhaust tone. But not the pops. Check with Jerry or check for any pending CEL codes on your car. Run a diagnostic on your car via OBD2 and the scanner might have "Pending Codes," that are lingering in the system to pop up, but haven't yet. For example, say your fuel injector is not functioning at its full capacity. So it might not throw a CEL at you right away, but it gets stored in the Pending Codes category that sometime soon that code will throw a CEL, but not yet.

Yeah, both my files can't get the exhaust to burble which is unfortunate. I wanted to upgrade the mufflers because I've seen some people with C400's replacing their mufflers with C43 (performance exhaust ones) and you can pretty much replicate the sound of a C43. Can't really find those but CLS63 ones are easier to find and would be an easier fit I think. Tbh I don't have a diagnostic tool or know anyone with it. Not too sure if I want to go out of my way to go to a local shop just for this specific thing. Even if there are pending codes, would EC even be able to do anything on their end by sending a new tune?
However, I have a few questions:
1. Are you running a regular Stage 1 tune?
2. Are you running Stage 1 tune with burbles?
3. Are you running Stage 2 tune (with cat-less down-pipes)?

That I do not know, personally. I only mentioned and explained about the pending codes because @loungn14 mentioned it above. Idk if they do play a role or not. I would best check with Jerry who sent you the tuned ECU file or Loungn14 and see what it could be.

1. Are you running a regular Stage 1 tune?
2. Are you running Stage 1 tune with burbles?
3. Are you running Stage 2 tune (with cat-less down-pipes)?

Ok, there should be burbles then. Check with EC about it. I was running Stage 1 with Burbles and i had plenty pops during declaration.

I would do a cat delete, I got burble action off cat delete alone not a lot but a few then added catless dps had even more when which I was surprised myself then added state 2 tune from Weistec which has been an ABSOLUTELY AWESOME EXPERIENCE ! I didn’t choose burble option because it already did enough for my liking but either way I bet if you do a cat delete or res delete whichever is the one where an x pipe would go, and run a straight pipe where the cats were you will get a much better sound and didn’t even get a check engine.

But one thing I would advise is not to run a burble tune with cats on. It can or will, after a long time, damage the cats because you're dumping extra unburnt fuel into the exhaust and cats don't do well with unburnt fuel. Some might experience this damage quickly, very late, or never. But there is a potential for the cats to go bad. My O2 sensor went out which I believe was due to the burble tune in December 2019. But, that was for me. you might never experience it. Just saying.

I had the same issue when I requested for a burble tune for Stage 2. It didn't work as EC said and I disconnected the battery for 2 hours, but still, didn't work as expected. So I went back to the original Stage 2 tune.

Lol I might've mentioned the risks of running burble with cats on to you earlier as well. I don't remember lol so my apologies for trying to be a smartass lol But yea, talking to Jerry would be the best option here since he makes the tunes. He couldn't fix my Stage 2 burble tune. He gave up after 2 additional files lol said it will have to be a custom file and that would be extra...so I just let it go.

I put together this site, tunedmercedes.com, last night and it was one of the first things I posted: http://tunedmercedes.com/performance/resonator-delete/
I also did UPD air intake spacers and K&N filter, that made a pretty big difference as well in terms of intake sound and power.

Asked for a tune with just the burbles and it worked. I can't really hear them how they sound like from the outside on the inside even with the windows down, but when you're outside listening to it, it sounds good. Everything on my exhaust is stock, so the burbles are more quiet, but sometimes there are more violent ones at 4-5k rpm. It smelt bad when I was revving it in park after I flashed it. Do any of you think CLS63 mufflers would improve the burbles?
