2014 E63S; AMS 100 octane ecu tune; edok tcu tune; BB intakes; dyno tuned
Has been approximately 100miles since I disconnected the negative terminal overnight to reset the TCU. Still feels less snappy and punchy, especially past 5th gear. In sport+ doesn't push me back in seat like before.
Have taken your advice and ordered a Dragy. Should be here in a day or so. (Mb service advisor not very proactive in helping figure it out... "No CEL, no issue". )
When I do set it up, should I just do some launches and share the results here? Will it provide any insight into HP/torque/has pedal etc? If not, how will it help?
Thanks.

with the dragy, at your own safety and regarding the safety of those on the road, and at your own peril (gotta get the legal out of the way):
- run several 0-60mph and post results
- run a 1/4 mile
- run a 60-130 .... this will spotlight your engine power thanks to gear ratios at these speeds ... like a poor man's dyno
plenty of dragy data in the sticky in the tuning section to see baselines of what your car should be doing in these metrics

We discussed those exhaust flaps before - you'll need to find another dealership. It's unfortunately as simple (and likely inconvenient) as that.

Yes I am starting to think that too. Have a couple questions:
1. If the exhaust flaps not opening is the cause of performance being affected, then wouldnt it cause issues normally when flaps are closed. In other words, partially opened flaps still better than closed flaps like in comfort mode ....?
2. What would you say to the dealer to make him check my exhaust flaps in the absence of CEL and just based on my butt and ear dyno?
3. Where exactly are these exhaust flaps located? Near the exhaust tips, or by the turbos?
As always, thank you all for the help in figuring this out. I get OCD when my baby doesn't feel right and have no where else to discuss/brainstorm/seek advice than here... Appreciate u all.

the ideal thing to do is log your car with hp tuners or an advanced scanner that can log your car ... then you get data like IAT, fuel trims, boost, wastegate duty, timing, among others. This is the core data to determine how your engine is optimized for performance
you can start by finding the service invoice from any member here in those threads that had no CEL but had power loss due to flaps and take a copy in to the new service center. DM the person you find here that posted their resolution and see if they are willing to share the invoice.
Also - since things are so muddy at this point - try going to test drive another used w213 amg and see how it feels; ocd messes with the mind and makes us sometimes believe things that aren't real - not discounting you just offering another perspective

Again, this may not be the flaps but they may not have any effect at low end speeds or power.

you need to get to a point where you simply enjoy this car and the driving experience. I've been where you're at, focused (perhaps in my case obsessed) with little details that drove me crazy. I had to let it go once I made sure it was as best as I could get it.
Keep the beat, this will get solved.

also you can take the car to a local tuner that has a dyno and have them check the logs of the car, it may cost you dyno time and diagnostics, $500-800, but could be well worth it - solve a problem or bring peace of mind. My local tuner is AMS and they are great helping me with this stuff if I need it.

By the way, if the car launches with race launch normally, does that rule out an exhaust flaps issue? Still getting 0-60 in 3.4-3.5 secs.. with built in track pace app. Thought I'd mention that here too....

Lol glad to know others get as OCD about little details like me too! Yes I will update in a week or so after I take it to an indie Mercedes specialist I have located in town. Thanks for the support !

OR... the car is fine, but the real metrics (imho) are 60-130, 1/4 mile with trap speed
hopefully the specialist can log the car and check those and other parameters
