Throttle lag from stop
Just an observation. The lag in my car was so bad I HAD to drive in sport mode not to drive this thing off a cliff. I have had the MCT adapted as recently as last summer so that is not the issue.
Well, about a month ago, I replaced all the cam sensors with the updated part number and cleaned the electrical connectors of the pools of oil in them. Cleaned the cables as far as I could go (CRC electric spray works wonders, and I went through two cans). Reset ECU and it has been quite phenomenal. I can drive in Comfort mode now (not crisp but definitely livable) and I even had to turn down my Pedalbox from Sport due to the much-improved throttle response. I was expecting it to get back to crappy normal a week or two later, but nope, its held on!
Something to keep in mind if you are above 40k miles

Good info
did you test each step in your resolution process to see what of all those three or four measures was most efficacious?
i wonder how effective just resetting the tcu alone would have been but I suspect you did that first

Obviously, the cleaning of the oil and changing the sensors go hand in hand, the leaking sensors caused a pool of oil in the electric connections and has been wicking toward the ECU for a while now. MB dealer replaced one of the sensors before and replugged the dripping oil plug into the new sensor smh. I could not even tell a difference between the new sensor and the old ones so I replaced them all again.

SprintBooster? That's one option to get around the lag. If you have a tune though, I wouldn't use the SprintBooster. I tried that once and the car (although its a M156) had a couple of scary episodes. Went into limp mode in the middle of the freeway! Ugh.

I ran both the V5 Eurocharged tune and the SB together for about 3 months. There were only 2 bad events during that time. In both instances the car went into barely able to move right after trying to jump on it at very low speeds to get around someone holding up traffic. It seemed like a combination of sudden steering together with hard SB amplified throttle was the cause. After removing the SB, I have never had the issue reoccur in the last 2 years roughly. I posted this in a prior thread that I don't recall at the moment and there were responses that other people sporadically had issues with the SB. Can't say if they had tunes though.

I believe I paid about $35-40 apiece back then. I spent about 45mins cleaning the oil and swapping the 4 sensors (easier than changing the air filters on this car)
