C400 Back from Dinan...
Who knew?
The Best of Mercedes & AMG
A long screw driver with a small blade inserted between the white locking portion (which slides back when unlocked) and the black portion of the connector itself...then a slight twist...and you can feel the "click" once the white lock portion is unlocked.
Then you can pull out the connector from the intake pressure sensor.

Hello...hello....hello.....

Well, you can never be too careful....but a sharper photo would likely help.

Just watched this https://www.youtube.com/watch?v=GA7Nv7UjtZE
stock c43 with 367 HP/520NM vs tuned c43 434HP/643NM



In other words, if we're getting 40/40 and considering RennTech's dyno rated us @ 375/398, that takes us to roughly 415/440..........nothing to sneeze at.
So when also considering the 4-matic's grip, I hazard a guess that the extra is noticeable, and while probably not anything mind-blowing, probably something our butts will DEFINITELY feel. And like.
In fact, if memory serves, someone here has posted we get some serious extra oomph in the mid-range, already a strong suit. Go-to-jail speeds come quickly in stock tune.Better still, I've done basic upgrades on other vehicles that added about 15-20% more HP (30-40 something) via SLP or equivalent Cold Air Intakes, K&N hi flow filters, Flowmaster 40 series muffler upgrades. I felt that, so I'm optimistic.

First time I've read about the limp mode / check engine light issue...something to watch for I guess.
