This is the highest tuning result I have ever seen.
But what about stress out the engine ?

MBWorld Fanatic!
Tuners update their tunes as they learn more. Some keep track (for instance Eurocharged is on version 5 for the M156). The M278 requires a bench tune (vs an OBD tune) so the ecu has to be pulled and modified. Weistec claims 540hp/616ftlb so those numbers are in the ballpark. Better downpipes / catless setup and you could get a few more. Wringing out the last few ponies at the expense of the engine isn't good. I'd be sure to go with a trusted tuner with a sterling reputation. Cocobeex who tuned your E, and are you happy with it?

But, i am always seeking out more power.
Also, looking into Downpipe, but so far, dont know which one to go with.
I might give AMS a try if they really hits that high HP/TQ.

2014 E550 4Matic with P1/LED/Pano
Given this motor has a higher factory rating in the S550, I'm not too surprised.
Has anybody fixed the transmission programming yet? I'd love a faster car but the transmission wants to save gas (5th gear at 25mph?? Blah).

OP, did you end up going with AMS for your tune?
I had it narrowed down to Renntech & EC, but I was on AMS' website last week & saw their numbers. Unfortunately they aren't as big in the MB nation as they are in the GT-R world. Hard to find a lot of info about their tune on the 550s.

I think you should listen to this video from the owner of Vinny Ten Racing and learn some of the implications. The guy is highly entertaining and he is funny too

That number is astounding considering that all the other tuners are around 605-615. I just can't find anyone that's running an Alpha tune on a 4.6. I contacted them & they don't have any video or other feedback to give me other than the website numbers. I wanna see numbers from someone other than themselves. If I can't find it I'll probably end up running the Renntech. Besides, someone in another thread told me that they're just numbers & w/o outside "proof" they're just that. So we'll see. Hopefully I can find some info. Some tuners act as if it's not a 63 they're not that interested.
