ahh yes 100%, gosh that would be amazing. I'd even contemplate getting one if that issue could be resolved but then I guess that's why the OP made this thread that we hi-jacked
I'll speak with my guy in Germany if he's able to do anything with my car regarding torque limiters....if he can do mine, i'll make him famous (and rich)
and dont forget to get back to us here on this thread and let us all know how that goes lol
I just had a look at an old youtube vid of mine and it looks as though the shift on mine happens just after 130 according to the speedo...I guess there might be speedo differences vs rpm at work here perhaps?
Yes does hold peak power well though. Even up to 7800 it holds onto power well. here's my dyno - i want to re-dyno again soon though as i'm positive that my latest VVT changes up top will have flattened peak power above 6500rpm even more than here:
I think the question everyone wants to know is....is this by brake boosting off the line, or if you simply stomp on the pedal after about 1 foot of rollout...?
first pull which caught me off-guard scared me. I'm not sure how I then managed to hang on with the two actual proper runs....maybe his car heatsoaked a little....? i dunno...no idea. The CLS would have been RWD (UK/Euro spec)....I don't remember seeing red calipers...but it was late and i was exited and being silly, so it all happened so quickly I tell you what though - shifting at my new 'racing-only' shift point means that i don't land at 5000rpm and in the lower part of the powerband, so it's pretty much ~500rw all the way after first gear.
After the TCU update the truck launches like a rocket both ways of launching. If you just stomp and go it picks up instantly and then a moment later the turbos get on boost and it rockets forward. Doing a brake launch it’s even more violent since there is no waiting for boost and you can spin all 4 tires in a 5800+ Truck in this cold weather.
It looks like your car is tuned with the redline raised about 500-600 rpm? This will help a lot with the issue of falling back to far down in the rpm band after shifts you should be in the 5500+ range now which is ideal. I wonder how the valve train will hold up to the high rpm over time?
Small update - I spoke to my guy and he said he can't raise the torque limiters on the M157. Sorry gents

sorry buddy, I just saw your post now. Yeah stock red line is actually 6700 on an M156 (event hough the tacho needle goes up to an indicated 7200). Mine is set to 7800 (I don't do it often, but it shows 8000 on the tacho). I have SLS tappets....I'm praying it holds up just fine
