Just bought an e55, how do I find who tuned it?




So far, I've found:
ARH headers
180mm ASP pulley
EC heat exchanger (system has not been split)
This is my first Mercedes, and one heck of a car! Love just about everything except the gas mileage
Definitely send the VIN to Eurocharged, they might be able to tell you more about the car's history and might even know about additional mods you haven't found (yet).
My advice would be to exercise a high level of skepticism about the car unless you have very detailed service records with it. Get it checked out professionally and do the basics (oil/filter, brake flush, transmission fluid change, crank position sensor, new IC pump). Find out what kind of plugs are in it. Stock or colder... do a compression/leakdown check on all cylinders.
Then drive around for a while and get some datalogs.... find out how the IATs look under normal driving, see what kind of AF ratio the tune is giving you. Those things will give you confidence that the engine will hold together when you decide to really "let her eat" on the open road.
The previous owner may have gotten everything right and perfectly tuned and optimized, but then again it could just be a collection of mismatched parts that need some sorting out. Better to take your time and go through the car systematically, then to trust that the PO didn't make any mistakes along the way.

Considering I assumed the car was stock when I bought it and had it shipped, it was certainly a nice surprise!
99 Electric Green vert - Eaton swap
99 Black coupe - built motor, auto, built rear, Borg Warner S475

I've had... 8 mustangs I believe? The AMG is car #41 in the last 11 years.
I had planned on running a trunk mount res and a bigger heat exchanger so the EC unit may or may not stay. I just know I'm a lot further along than I expected to be.
Thanks, I've been doing a lot of reading, love the car!
Alright, so Jake (at EC) says it's not their tune... guess I'm on the hunt.
Eurocharged
Renntech
Dyno Comp
OE doesn't save by VIN but they're looking into it
Vivid is checking with Kleemann
BI, you haven't touched the car... have you?

This makes me want to put a wideband on it IMMEDIATELY to see if there's anything going wrong.
Maybe you can by an ez flash from OE or EC, load the current map onto the device and then onto your computer and send the file to your preferred tuner via email

But still get some monitors on their and due a dyno/street tune to finish her off

GL and nice find!

You are so intelligent!!!
No worries, man
Already talked to DynoComp and they said it wasn't them.
The car has been running great so I had a little fun with a couple people on the freeway this weekend. Not sure how you all feel about runs in Mexico in broad daylight with light traffic but I have a couple vids. Based on results, I'd say the car is making about what it should, lol.
