Anyone solve this lol i want a 14 or 15 c350 coupe but there hard to find with the options I want. It would be a hell of a lot easier to find a C300 with what I'm looking for, but I don't want to buy a 300 and then be stuck with less HP. I can't believe no one has dyno of before and after except what like 1 person? I emailed Cory at kleemann he didn't have physical proof either.

Guys any update on the Kleemann 300 hp claim. Did anyone have a chance to of the AWD Dyno... I have been following this thread closely past couple of months since getting a 2014 C300 Sport 4Matic.
There have been positive results for many based on what I have read in the thread. Still a Dyno AWD would be awesome from anyone who has done the Kleemann or Eurocharged tuning for M276 engines.
Thanks in advance.

I contacted Kleemann and they said they weren't willing to give a discount for a dyno results which seems fishy to me. He said he has been burned before going that route. I have connections via an old job to an AWD dyno to finally put an end to all this grey area too.

When are you planning on getting the Dyno done 97GSX

I have spoken to them previously, and I do believe them some but hard numbers don't lie...

There are valid reasons when it comes to dynos honestly. Heck, 1/4 mile times are probably more consistent/ better and mean more to me, and you can't cheat them....

Agreed but go find me a tune people bought frequently without some sort of number or proof behind it...especially for $1,000. You need to have some sort of proof showing you can backup what you say.

This is what I got everything before 110 and 115 are cats (1) (2) = 4 cats right?

Hey gang,
Getting ready to order the ECU from Kleeman, sent an email inquiring about details. Being that I'm not in Colorado, it sounds like I just remove my ECU and ship to them then they ship back after $1300 worth of magic has been done. Which leads me to my question, does anyone have a good walk through or guide as to how to remove the ECU?

Kleeman Tune Feedback
I recently purchased a 2013 C-300 (M276) motor and after reading all the threads on this forum and speaking to Kleeman I made the decision to pull my ECM and send to them. Over the next week or two I will supply feedback on this tune and offer my opinion as an enthusiast if it is worth the step price tag.
I will drive the car for a few hundred miles and put it through the paces.

Would have been ideal to have a dyno before and after ECU upgrade.

Kleeman Tune 500 miles later
as promised here is my update on the Kleeman tune on my 2013 C300 - M276 engine.
I removed the ECM and overnighted it to Kleeman, Corey sent me an email the next day when they received it. They programmed it the same day and fed ex it back to me. At this point all good. Reinstalled ECM and the car started right up and no check engine lights etc. All good. I requested Kleemann to default my eco mode to off instead of on and for some reason they either forgot or missed that programming change. I emailed them and explained they missed it and I learned something I was not expecting, they told me the programmer was actually in another country but would look at the log and see, a few days later they told me they did do it....I explained to them again, they missed it....if you have one of these stupid eco cars you know how they shut off at traffic lights when certain operating conditions allow for it. The resolution they came back with was for me to take the ecm back out again and send it to them and they would do it. I have to decide if I want to do that and be without wheels again for 2 days. Blah.
Now onto the driveability - first off, I only drive this car with eco off and the tranny in sport mode. My first impression was the throttle response and the throttle feel is all around better in all driving situations. The claim of 300+ HP seems to me to be heavy, no doubt it drives much better and feels like the engine now hooks up with the tranny better. I think the tranny needs about half a mile to learn the full throttle or something along those lines because in the first full throttle application she stumbled on herself right after install and I thought to myself thats trouble, but it has not done it again since, I now have 1500 miles on the tune and it has not skipped a beat. Its hard to believe MB tunes these cars down, this tune does not feel like you added a turbo or did anything crazy to the engine and if you drive it like an old lady you would never know you had a tune done. Its not really a night and day tune like when you tune a turbo german car, but its still noticeable. When you get on it, she goes much better than before. My wife also agrees it is much better and she noticed the difference right away. Now for the price....and the programming issue with the eco - kleeman did everything quickly, but not accurately. I'm happy with the performance tune, unhappy they forgot to change the default on my eco, and I dont feel like the high price is a great value. It is the easiest and fastest way to gain some HP but the price seems too high, now that I have done it, I dont regret it, but I wish it was about half the price, that would made me feel like it was a homerun.

Had the tune done the other day, There is a huge difference on how the car drives before and after. Completely different, instant, response to gas paddle, and the car pulls a lot stronger.
I used to drive g37x and right now c300 feels on par if not better, in my opinion feels like it pulls a bit stronger now than g37x so the claim of closer to 300 torque feels about right.

Did some runs 0-60, mostly it was in the 7 and a half range, keep in mind I'm in Denver, mile high.
Reviews for g37s Mile high put it too about same range 7 and a half, and that is 330hp coupe.
Pretty amazing for a 250hp car after a tune.

Sounds pretty promising. Is you car out of warranty yet ? Any chance of getting dyno done .. So someone can finally put an end to all the speculations of numbers by Kleemann tune by posting actual numbers.. This entire thread will be grateful. Thanks in advance

I'll pitch in a few bucks to like a "gofundme" if we get this last person that claims to have a successful tune done to go get a dyno run done.
