Mercedes Specialists "Carlsson", is also bound to release something for the W/S205 in the near future. They offer their own warranty, but it is not MB sanctioned like the Brabus modules, where you can get your MB dealer to sell and install it.
In real life the warranty that Carlsson offers, can get complicated if you run into problems, and try to claim the warranty via one of their dealers.
I say this, not to expose the sellers as not wanting to live up to their warranties. In some cases the root cause for whatever problem you get, is not from their product. So the seller can have a legitimate right to refuse coverage.
If MB takes the same position, you end up between a rock and a hard place. It can be impossible to prove who is a fault.
With the factory backed modules like the Brabus, there is no discussion who is responsible.

Again if you spent 50-60K why quibble over a few K? Every time you modify your car the probability of problems goes up significantly, knowing that you're covered if something major goes wrong is worth a lot. The same is true with any component. People love to flash expensive cars, when things go south and they figure out that parts are 3x more expensive than the car itself many end up with shiny adornments in their driveway. Mercedes dealers count on expensive maintenance and repairs for their bottom line.

Reading the thread it appears this isn't much of a technically oriented crowd. I've started a post on n54tech to share the C300 tuning details and developments. I'll post all future updates there for those interested.

Yep 90% of tuning chips owners use them for racing only

Also, I test drove the c300 last night. My friend smokinjoedc (MB forum member) bought a w205 c300 last week. He also has a 2014 w204 c250 with BMS JB Beta tune. The c300 is a HUGE improvement over the c250 1.8 cyl turbo. There was little to no lag with sport + mode activated. Similar to how Sport mode is with the JB Beta on the c250. We drove both cars back to back and he thinks his c250 with BMS tune is still faster off the line. I told him that you got 14.1 quartermile with brake torquing on the c300, using the vbox and he now has high hopes for the c300.
I informed him that you are looking into making a tune for the c300 and he is very much interested. We will be following your progress.
thanks again.

Anyway...When Renntech or Kleemann comes to the w205 forums and provides updates or ideas/products and actually provides feedback/comments to forum members, you can PM me. Meanwhile, while we have a vendor on here who is trying to do something for us and extract more power out of the w205 (which will also help persuade my decision to buy a c400/c450 over a 335 or Audi S4) I will rather follow his/her progress while you guys continue to nag and complain about what Mercedes engineers could have, would have, didn't do.
I followed Renntech, Kleemann, Eurocharge and Carlson threads on the w204. I was not favoring BMS. BMS was the only one who chimed in and was actively responding to the w204 forum member questions.
By the way, I have Eurocharge tune on my c350. That should say something right.
bye.

No.....
We have a vendor who is here on business. He is here to push his product and make money. He is welcome to do so in my book, but be honest about it.
Right now Terry is planning to come back. But only after enough people have expressed, some even begging him to come back.
If he comes back, then he will start a new and fresh thread, where he writes something in the opening post to eliminate any (To him) instruders.
On top there will be a few Goons/Followers, (often younger guys looking for a discount) who will shame and attack anyone who dares write somehing opposing to the Delicate Genius.
I have seen this scenario play out so many times before.

Thanks Terry. It's pretty sad that we have to switch boards to follow progress of your tune as we have a few members here that cannot, will not, accept the fact that you are trying to help us here instead of providing negative comments. We did appreciate your efforts more on the w204 forums and the members there were really knowledgeable and very receptive.

I for one am excited to see a vendor working on developing a performance product for the W205 C300. I came from Audi and I have a B7 A4 2.0T with APR software flashed on it 2 months after I bought it new.
Did it void warranty? Yes but I had it installed anyway and it's been on the car for 8 yrs.
Can't wait to hear for more information on your progress. I'll be following your thread on N54tech.

Terry, thanks for the great update. I came from Audi and had an APR tune on my car for 5+ years without issue. I think a properly done tune can be great fun. I actually have high hopes with the C300 engine, I love the car dynamic and the chassis and the engine characteristics. I think the car will be just about perfect with around 280hp and 300tq. Not sure if it is achievable but I can hope

I don't understand why there is so much negative feelings. Someone is trying to do something for the community.
If you are not interested in tuning, just don't read the thread.

The vendor is not here to help anybody. He is here on business.
You do not have the right to tell people to leave either.
I have to question your motives for making such a one sided post.

Despite that, all of us oldies are well aware that the aftermarket is full of shady guys selling stuff like the "tornado air" and another myriad of hucksters.
http://www.tornadoair.com/
Even more legit aftermarketers sell stuff for which improvements are dubious or marginal. Cat backs? Useless. Fuel lines made of exotic metals, strut brace bars, useless, useless, etc. Heck even car manufacturers themselves pack cars and advertisements with stuff that is of marginal or dubious use, and people love them! Ever heard of a fragrance dispenser?

Its not about negativity. Hey if someone wants a tune that's fine, however, they should go into it with wide open eyes. When you're 20something you are a little less experienced, so its nice for others that have been around the block to give them a heads up. I don't think that tuners are out there to blow up anybody's engine or to rip anybody off but they are out to make a buck.

B.S.
I don't blame Terry for moving updates on his research/results elsewhere. What happened here is juvenile. BMS has been around for quite some time and they sell a product that tens of thousands of people buy and use every day. The responses/reviews to what they make have been overwhelmingly positive. Yes there is risk involved with engine tunes, and I probably wouldn't buy one myself, but I am absolutely interested in his research and results, and I believe many others would have been as well. I believe that people here would have been able to see first hand what what goes in to an engine tune. I say let people make their own decisions.

Let's face it, the Mercedes demographic is significantly different from those that buy a BMW 3 series. Tends to be older and have different values regarding car ownership and modding. So I'm not surprised to see BMS get this type of reception whereas on bimmerpost he'd be welcomed with open arms.
I wouldn't be modding the car either while its under warranty, but 4 years from now? If I can extract 10-20% more power that would really breathe new life into the car. My x5 is nearing that age and I'm considering it given that it has the n55 turbo.

Please continue Terry with your development.
Trap speed of 98 at 14.1 and high 5's is very good starting point.
Stage one with a splash of E85 or 100oct.. I think you can break in to 102 trap speed at 13.8's
I bit a better rubber and wider wheels might be able to break into low 5's.
what was the IAT during WOT? air to fuel ratio look rich?
Cooler California weather should help a bit too.

C300 tuning has been running strong. Went back out tonight for some testing at the same private track, temps in the low 50s, on E20 fuel. 91 octane + 3 gallons of E85 mixed in. Results were impressive.
