Nicee now let me ask you this, with the brabus chip does it increase the sound? I like burbles with pops, my car burbles a little on S+ but I honestly want something louder. Obviously not too loud because I don’t have a V8, however I do think the 53 engine sounds good when it’s tuned with downpipes and stuff.
oh okay that makes sense, that’s why it’s +80 HP and not 40-45HP like I see from other tunes. I think this will be good power for the GLE 53. I think I’ll do this tune sometime next week. The shop said that a stage 2 tune will cost more than that but it will put me at about 550 HP, so I’ll start at stage one and see the performance difference and possibly go to stage 2.
I'm curious about this. I thought Mercedes uses recirculation valves and not blow-off valves to keep the turbo boost high. With the increase in power, Renntech recommends upgrading the turbo so they aren't dealing with the ok bcreased pressure...BOV would resolve this but also decrease performance.
Have you considered upgrading the turbo instead of the BOV and get better performance and reliability for the same price?
So I talked to a few different tuners like rentech, eurocharge, brabus etc, I’ve decided to go with eurocharge tune I’ve heard great things about them, highly reputable and their stage 1 ECU tune brings me from 430HP to 545HP, This is more HP than the other tuners achieve at stage 1. I’m going to go stage 2 later on but I want a feel for the performance difference first. Unfortunately I was told that any Mercedes after 2022 comes with a locked ECU, so I have to get my ECU shipped out of the country, get it unlocked and have it shipped back and tuned. ( oh yeah and it’s $1000 to unlock a ECU) That’s crazy I could have saved 1k if my ECU was already unlocked… I was told this process takes about 10-14 business days and I’m going to drop my car off on Monday to start this process. I will keep you updated here once I receive my vehicle after tune.

I’m not going with Renntech anymore, they are really expensive and I can get more performance from eurocharge.

I was looking at Eurocharge for my 63 but can't see any info on their website. When I search 2023 GLE it says no products found.
Renntech gives a nice 100hp boost but yes, it $3800 which is crazy for a stage 1 tune. You can also do it via the OBD port which is handy. Would like to see some details on what Eurocharge offfers.

With eurocharge you would be at 693HP and 705TQ with Stage 1 ECU tune for $2K assuming you have your ECU unlocked, if not it would be an additional $1k. For stage 2+ numbers all you need to do is call them they will tell you the performance increase. I don’t think they publish the numbers because it’s different for every car depending on what kind of parts you get for stage 2+, Since stage 1 is literally stock just ECU tune numbers would be the same for all the cars.

Thanks for the info... I'm still not understanding why it's considered to be a better deal than Renntech? They give you the OBD tuner so you can tune or de-tune as needed, plus their stage 1 gives 745HP and 767 torque for $3840. When you add in the ECU unlocking fee, they are pretty close in price and you get more power from Renntech. Am I missing something?

Eurocharge also gives you hand held to let you switch to stock or the stage 1 tune, Honestly I just went with what gives my car the most power, rentech stage 1 would only bring me to 505HP and it cost a whopping 7K, So for the 53 rentech is not worth, 63s maybe rentech is able to get more power from stage 1 then eurocharge not sure. If you like renntech numbers more than eurocharge then go renntech, They are also very reputable and reliable just more expensive than other tuners.
I'd expand on your question and wonder why it's all talk about horsepower gains.
Why not usability, drivability, torque curves and things that affect the performance that you're interested in?
As I understand it, although the Brabus 500 only adds 60 horsepower, it fattens the torque curve significantly.
Those are things that are more interesting to me than simple horsepower figures.
I mean brabus and eurocharge stage 1 TQ numbers are very close eurocharge just adds more HP, and yeah it’s not all about HP but I started this thread specifically asking about HP so that’s why there’s “all this talk about horsepower gains”
Are you just doing a tune? No downpipe/ exhaust modifications? I was planning on going euro-charged on my 21' 53, along with a catless downpipe.
Yes eventually, I’m starting at stage 1 first before I jump into stage 2+, I want to feel the performance difference from stock and stage 1 tune. Then I’ll go stage 2 and get downpipes, upgraded turbos etc..
NO ONE except Renntech or Brabus offer a warranty. Eurocharged and OE will run and hide if anything goes wrong and blame you!
Im not sure about that one, Eurocharged is very reputable. I did a lot of research into all tuners and I’ve never heard anything like that about eurrocharged they are trusted…
Ok. They will NOT stand behind a tune if your engine goes boom!
Interesting, well you know more than me I’m new to tuning so maybe you’re right. My question is how can eurocharged list a warranty for 2 years and $50k engine repair if they just “run and hide” if something breaks, wouldn’t that be illegal?
