As for the third option, I'd email them to ask. I think it could work???
I have narry's tornado box, haven't installed yet due to awaiting 30k service and a dyno run.
I hope in a fews to have this installed as well as the charge\boost pipes. my goal is at least 250hp so badge on the rear of the car isnt a lie
I also have the t box which is like the tmc transmission flash. Now That i have used and can say that the car really does move and shifts are a lot faster and fluid when flooring it. And when using the paddle shifters in e or s have a much quicker response.
normal I donot like to compare other people products
but since people asking I will reply
our box is only box in the market which can adjust 4 channels
1 is boost 2 map 3 fuel pressure very important if you change mid pipe and muffler 4 is turbo valve
now I must say even this brand cxx which cost more than thousand dollars
doest adjust fuel
I see most of the people changing mide pipe and muffler to sports type
after you change this your turbo boost goes high so what point in buying a box which only adjust boost because it will not work
but most of tuner for benz only test the product in brand new car without any modifications so buying a box which only does boost pressure is useless wont give more power at all fuel adjustment is key
also we also provide tune software which very easy to use just put some number and the car is tuned with each and every tune box for free including obd2 elm interface free for diagnostic
because for example you living in hot place you can adjust it
or you in cold place can increase more boost
I hope this answer most of the question
for more info can email me at newtongsm@gmail.com

Here is the PDF with installation instructions from another dealer of Speedbuster/TMC rebranded box so exactly same installation: https://www.kochtuning.com/data/medi...-135-150kw.pdf
There is also RaceChip discussed sometime on this forum.
There is also an Italian tuning box called Seletron which is also providing software for adjustment of parameters for dealers of that box, same for DTE Systems(Germany) tuning box which is a rebranded box from TuningBox (Belgium)
These are medium priced tuning boxes for the 250 CGI engine.
There are also expensive ones like Carlsson C-tronic tuning box/ Kleemann (which was a rebranded Steinbauer tuning box now they have something inhouse) / Brabus tuning box / KW-Systems tuning box/ Vaeth tuning box.
Most tested of these tuning boxes and dyno-ed are TMC/Speedbuster and DTE Systems from what I found on internet and other forums. Also Carlsson is discussed on this forum.
