I remember reading back in the day GM dummied down HP numbers and performance on their cars, so nothing was more powerful or faster on paper than the corvette. Obviously people figured out a few ways to modify cars like the 1973 455 trans am, with some simple timing advance, blocking of the EGR valve and bigger carb jets, it would be faster than a Vette.
It would be awesome to see a all wheel drive C63 S

I definitely agree! With launch control the 43 is hitting 60 in 3.3, the 63 can only manage 3.9 because of traction issues.

All wheel drive C63s is called the E63s. What you might wish for is a e63s coupe. Which I think would completely canilablize C63s coupe sales.

AMR is claiming with their new "Launch Control" the C43 can achieve 0 - 60 in 3.3, 3.4
This is the achilles heel of the C43 for me, first gear boost cut is ridiculous. It feels like all the boost is being diverted on a hard launch from a stop. Then the car makes up for it once second gear is achieved and I doubt this is turbo lag as I can feel the boost build and snails spooling up- just not getting to the intake somehow. Wish they left off all of the electronic safe guards crap and traction control. I bet this thing would launch like a bear on fire.
I never got tire spin off of a start from stop launch and I dont brake boost because I feel it bad for the tranny if done too many times. But natural tire spin of the line on this car would greatly enhance 0-60, my point is I dont think its turbo lag holding it back, its all of the silly traction control and other things holding it back, besides MB does not want this car to be faster than the C63, so I bet they dial it down in first gear. Why buy a 63 if the 43 is faster, duh
And somebody should post a vid on how to remove the MB wire harness clips for the piggy install.

What launch control on the C43? Increasing rev limiter and calling it launch control is like me putting a melon sized motor in the trunk of my car and calling it a hybrid.

Berger won't ship or allow pickup for any residents in CA. Anyone know how to get around this?
Does anyone know if the JB4 connected via the ODB2 port all the time?

I believe that the JB for the C450/C43 requires the unit to be plugged into the OBD port for power? Not sure on that, or if there is a separate power source that isn't shown in the installation instructions. To get the most accurate logging it will need to be plugged in to the OBD port, even if that isn't it's power source.

SICKOMODE!
I am also wondering if the JB4 can be used in addition to my stage 1 AMR tune.
With timing like this, I would have more fun with the car than I did with my MY2018 Huracan I just rented over the weekend!

Auto. I will try to make one. I have a good camera setup now.
You can get it before that haha. Just take it off before service intervals.
It is possible to stack tunes. But I do not see the need for that.
Thanks man! I will wait for the feedback from you about the intakes. If you see some gains, I will order mine as well.

Great thread going on. I will submit my numbers as well since i just got dyno tuned from EC. I will have new results this week just for comparison between the jb4 and EC.

1/4 mile, JB4 updated firmware
Map7, K&N drop ins, e30. Ambient temp was 45F. Bogged down 1st to 2nd and 0-60 was 3.82. I will get a better launch since this is the first time I did a standing quarter. Usually roll race since all my buddies are RWD. Of course done in Mexico 🤫
