Performance Upgrades
Hi guys, so about a month ago I bought a E55T and I really want some more power out of it. I'm looking for idea of what to do. Also I got a big warring by the head of service dept at my local dealer about do anything to the exhaust less I want such little back pressure that my car will be creating less power. Please through in any ideas that you guys know will make it more powerful and if all, sound better. I really want to invest my time and money into it and truly make it my own.

If you want more, you can go with a tune, some headers, a port/polish, or supercharge it (or all of the above). Look at Kleemann, pricey, but quality. Quaife LSD will get your power to the ground.

Starting with the exhaust would be easy. If you want bold sound, less restriction, and a little performance upgrade, go with the crossover pipe setup. I went with an X-pipe, removed secondary cats, and also removed the resonator. This will free up a little weight and sound so much better. Here's my thread https://mbworld.org/forums/w210-amg/...ipe-video.html

Hello,
Replacing secondary cats with an X-pipe & deleting the resonator is the way to go.
Cheapest mod, yet very very effective.
To help you decide you can see my feedback here:

However, I believe the crossover will have LESS scavenging effect in the wagon, because after the resonator the exhaust pipes merge into one.
Good luck,
Faiz

I've heard great things about Eurocharged tuning.
Others I guess are overpriced.
Also before I get a Tune, I'd like to install Shorties and/or pulley.
Good luck

Frankly, you aren't going to get huge power increases on these cars. Your best bet is to get rid of the secondary cats and resonator and add shorty headers.
What you can do right now is the ECU reset. Make sure you do this once a week. These cars have an aggressive ECU econo-tune that starts to kick in after about a week.
1. Turn off all electric loads. Lights, radio, cell phone chargers, headlights, etc.
2. Take out key, put the key in and turn to just before start. Leave it there
3. Gas pedal to floor (including the little extra push at the bottom).
4. Keeping your foot on the gas for fifteen seconds.
5. Keeping your foot on the gas, turn the key to off and leave it in there.
6. Foot off gas.
7. Remove key AFTER two minutes.
8. Drive regularly for about 2 minutes.
9. Have fun.
It doesn't always work. Sometimes, two attempts are required.

the only thing that can be reseted, via StarDiagnosis and only at ME2.8, is the self adjustment of the fuelamount, this depends on the values the O²-Sensors are measuring and is only used to get a perfect fuel/air balance. there is absolutly no need to reset that. Also there is a "Base Initialization" in this process the Throttlebody will be calibrated, but THIS can not be done without StarDiagnosis and takes around 30s to complete.
There is a Urban Legend that the TCU can be reseted in such a way, i tried this several times ... nothing happend, i verified via StarDiagnosis. Reseting the TCU means resetting the adaptions of your gearbox, that sometime can result in better shifting.

It's an ECU reset but it absolutely does affect the TCU.
I usually do the reset procedure then do a hard acceleration after a few minutes just to teach the ECU how I like to drive. :-)
And, yes, the W210 E55 ECU's aggressively start to tune towards better mileage after about a week.

The ETC/TCU priority is comfort and economy. A transmission service, blue top solenoid valves, AND maybe a TCU+ECU tune would fix part of the problem
