Transmission update is available!

Had my car out a couple of days ago and noticed the HP doesn't exceed 400HP on the infotainment system.
Posted a video of it hitting 416 ish last year. Think others saw up to 419 HP. Anyone else notice this>?
Wonder if it's just an algorithm update or did they deprecate power ... now that Emira 420 has lunched...
Going to get the Draggy out for a test soon.

I think it has been mentioned several times on the forum by others that the performance figures on the infotainment system are mostly made up & not to be believed - an algorithm as you state. I thought it was mentioned that a software patch had pinned it to max at 400 too. If you think about it, without attaching your car to a dyno it would be very difficult to measure the real horsepower. I wonder too if they patched the software to show 420 on the Sport 420?

Yeah probably a challenge to measure 15-20 HP. However, Car and Driver posted there est for the 420, think C&D posted the US 400HP car was 3.4s - to 60 and 11.7 sec on the 1/4 mile.
420 Emira
PERFORMANCE (C/D EST)
60 mph: 3.3 sec
100 mph: 7.7 sec
1/4-Mile: 11.1 sec
Top Speed: 186 mph

My last Draggy run was 3.5 -- 0-60.... I'll see if it lost 0.1 sec ...

I think this si just a software thing. My car has never past 400 even with JB4 map3 on E30 and Draggy improved numbers

With the number of glitches that appear to come with software updates, I am avoiding taking mine in to have any further added. I bought my Australian delivered 2024 AMG powered model the end of September 2024. At that time there was a transmission update which the dealer installed shortly after, with no problems.
From what I’m reading on our Forum, the latest transmission update sounds very worthwhile, but other updates, aside from transmission, seem to come with unwanted side effects.
I’d be grateful if some knowledgeable member could advise the pros and cons of other updates that might best be accepted or avoided.
Thanks in advance.

I have everything available in the US market and nothing has negatively affected the car in any way. I think there was something about track mode lowering redline or power output or something but that was the V6 platform not our cars. There's nothing I am aware of you want to avoid. There is also a recent rear light harness update that might be available in your region that fixes the incorrect current to the rear lights causing the intermittent rear light warning.
