Hey I was just thinking about tuning the 2014 E550. Was doing some research and this is what I’ve found so far.

Weistec: 540HP 715TQ ($1499.99) not sure how tune is done either shipping CPU or plug in like others now.

Eurocharged: 530HP 606TQ ($1599.99) comes with hardware

Renntech: 540HP 705TQ ($2480.00) also comes with its own plug in hardware.

Wanted to to see what people’s opinions were and if anyone with the tune has any valuable input on either listed companies.

Thanks!

I went with OE Tuning and I'm putting up lower than stock numbers. I don't know if it's an issue with the tune or the car, and unfortunately I don't know enough about the car to argue with them about it. I honestly want to go back to the stock ECU programming because, really, I didn't/don't need any performance improvement...

I know that Weistec and Renntech are reputable companies. There will be more people on the AMG forums that have actually used those companies to tune their cars and can provide feedback about them.

I’ll give it a look thanks!

Well that’s unfortunate. They won’t refund or re program the CPU?

Is your car still under warranty ?
If so, get 2nd ECU for tune. Keep original for MB Dealer service.

Just my 2¢

Huh? You bought a product and know enough to prove its making less that stock power but you don't know enough to argue with the tuner to have them resolve this issue that you paid over $1000 for? And you bought a tune yet you didn't and don't need a performance improvement?

I have a Eurocharged tune on my E550, and it is fantastic. I went with them because they have a local shop really close to my house. No complaints so far, been tuned for a few months now. FYI: with just a tune and muffler delete, I ran 12.4 @ 114mph.

Seriously??? Dude, you need to stop. If you have a problem with your tune, talk to Weistec and have them fix it. Stop trashing a company without giving them a chance to fix it first. If there is an issue, they will fix it. You're really making only yourself look bad at this point as hundreds, possibly thousands of others have use their tunes with stellar results.

Leonardick

Why should I stop? The vehicle not even reach its factory speed limit and this mean they've had messed up my ECU then it might cause harm to other components. What if I did not have the runs then I would never find out that they did a lousy job? You should have see the way they respond to my email. They shown lack of professional level, careless. Positive and Negative feed backs are the nature of rating business and products. I see nothing wrong here.

Hmm...maybe you should have posted that originally, or even answered one of the questions asked in your original thread, then people wouldn't assume things. Good luck.

Any others with experience running downpipe & tune on e550?

AB550

I went with OEtuning as well. Stage 1 was nice, but after loading the stage 2 and cat delete downpipes I don't feel much of a difference. They tried telling me that cat delete only adds 15-20hp and that I needed to do full turbo downpipes(with bridge pipes) for any real gains on their stage 2, which is quite different then what they said before buying the stage 2. They still have yet to confirm what the car should be putting down if not their advertised specs. Either way I'm gonna get the car on the dyno end of October when the hours at work slow down and hopefully get this resolved then.

cocobeex

Been there and done that.
My understanding, Stage 2 tune is for tuning out CEL that caused by Catless.
The gain is from downpiped catless.

It will not give you significant gain.
But if you are after power, every hp/tq counts.

AB550

Would have been nice if they had mentioned that prior. Either way 520-540hp and 700ish tq should punch you in the seat even at 4400lbs. I am after power, the kind that makes you giggle whenever you floor it lol... thought I was going the achieve that without pulling the motor.
