The only feature i like is you can tune it yourself. I've been having a nightmare with the cat-less down pipe, apparently the secondary o2 sensor on our cars is a wideband, its throwing ecu off in the reading the parameters. Car is running lean and its pinging under acceleration. I need to get this sorted out, I was looking into o2 simulator but Im not sure which one to go with? Any ideas or suggestions?
Not mercedes, but a great idea and understanding of how to install and what it does if you aren't familiar:

I do have o2 anti fouler installed, it took care of the check engine light. But the ecu on the c250 is really advanced and it can sense that there is something wrong with the emissions so it's using the lean a/f map. Car is running 10.4 and it should be around 14.7 under acceleration.
Are you familiar with the 02 anti fouler trick? That sometimes eliminates the CEL from the secondary cats due to running catless.

I have no tune. I've been looking around, but haven't made decision on what to get. I really want a reflash but since no one decrypted the ecu yet and the demand for it is really small for it might take a long time. Not sure if there is any tuning box or piggy back our there to optimize all the preformance parts I have on my car?

The only reason I don't own one right this second if because I am toying with the idea of trading in for C250 and swapping all my mods over
Brabus is very costly. However, Brabus, Kleeman and Carlsson are the only chips I have seen that actually look after your engine AND produce decent results. In the performance upgrade world, you get what you pay for

The TMC autoflash, is mainly for the TCU, used in conjunction with their piggyback its supposed to optimize the car. I've yet to meet anyone actually using the autoflash though so no feedback on it. Weistec has said they can calibrate our TCU so that's also an option. I currently run the TMC pedabox and that gets rid of the lag enough where the car is tolerable.......for now.

According to TMC, their flash will also modify the ecu map.
Importantly, they say it will work well with my carlsson piggyback and I should see an additional torque increase.

It's frustrating that there are so many tuners out there but no one wants to invest time into encrypting our ecu. I been in touch with Eurocharged, and Jerry one of main tuners said he never had a chance to work on a c250 cgi. They told me to ship out my ecu to them for testing. But I can't afford to be without a car for a week or more. So I'm thinking on getting a carlsson unit, I really like their safety features incorporated into the unit.

I contacted brabus in Australia but they won't sell the wastegate separate. Anyway it's just a wastegate, you could go generic aftermarket. Talk to a local turbo specialist :-)

You will be happy with the carlsson ecu and intercooler kit. It is awesome. If you are in Australia I could give you a drive of mine....

What I would do is check with carlsson whether their ecu without the intercooler is different. It may not be tuned for a larger intercooler like their CB20/25S ecu is.
Just a thought :-)

The Rado unit requires you to modify your bumper beam FYI. Still, with the size of the opening of the bumper......well part of it is blocked so not sure how effect that is. Even my OEM upgrade unit is blocked by the bumper. If anything I'd wish someone to make better intercooler pipes. Aus, any news about the diverter valve?

I spoke directly to them about it as I was considering it, then they told me the beam needed to be modified. Truthfully, the stock end tanks aren't that bad. Worse case is wrap them in some dei gold heat deflecting tape. I would consider an OEM upgrade as its plug and play, I think Ausmb and I narrowed it down to a c220cdi model though that's not what I ended up with. Anyways, don't wanna clutter Aus's thread, pm me if you wanna discuss more about it.

No word on the valve yet, I will email them later in the week.
I have been thinking about it, and I reckon solid intercooler pipes will make a positive impact on turbo lag. The oem pipes a are pretty soft....

Just spoke with carlsson usa and they assured me that the piggy back unit that comes with the intercooler is exactly the same as the one you could purchase by itself. The price price they quoted me for the kit with intercooler $2400 it includes all the shipping fees. $1850 for the unit itself with all the shipping included. What you guys think?

Well personally, I am very happy with the carlsson unit, so I say go for it. If you want a flashy intercooler, buy the rado one. As far as performance though, I don't think our little turbo could utilise something so big and I have had a great time with carlssons smaller, lighter and easier to fit unit

It's on par with kleemann and brabus if that's what you mean.
Really, only you can answer that question. For some people that's play money, for others it's a fortune. Personally, I don't regret my purchase, even though it came to $3300 or thereabouts by the time it got to Australia
