looking for more power after all this...

I have a 2012 E550 that I want to get more power out of. I have already done the following:
1- Eurocharged ECU upgrade
2- K&N Filters
3- Resonator delete
What else can I do to add more HP??
I thought about changing the downtubes but was told I'd only gain about 30 HP which doesn't justify the expense to me.
Who should I talk to? Help!!

I am also seeking for the answer!!!

btw,
Don't think Resonator delete gives much HP gain.

Glad to see some folks tuning these M278 monsters.

Unless you ready to go to Kleemann tuning there's really no way to add significant amount of HP

It doesn't. Just sounds good.

Somebody should know what else can be done to this car to get more HP or Torquee.

tune

It's over for this car, I am in the same position. You can go to weistec and drop around $20K, but will be cheaper to trade it and get E63.
Be careful adding more power, your tranny and 4Matic may give up - will be sky high $$$ to repair

Eurocharged did the tune for my E550 about a month ago and so far I love it! The car runs awesome!
I'm seriously considering adding down tubes and flashing the ECU again to go to Stage 2.
Why do you guys think? Any suggestions? What else can be done?

Mine: 2014 E550 4matic; Hers: 2016 CLS 400 4matic
How about improved intercoolers and an upgraded intercooler pump either that or down pipes.

Intercooler pump + down Pipe + 2nd stage tune.

All those cost = upgrade to a Pre-Owned E63 AMG ? close to it ?

Then, Keep modding on the E63.....Oh man, its like non stop

Except that he has a E550 convertible and they never made an E63 version of it...of course could go all the way buy a crashed E63 and do an engine transplant.
