went in for some suspension noise and they also updated the ECU with "Service Campaign Update"

I'll put up the code they listed tomorrow.

Car is back to stock on boost. What a difference... no more 3k to 6k passive HP pulling power.

The torque is not as noticeable, but i could tell I need more pedal effort to get the car to punch through traffic.

Calling OE to set up ref lash and I might go to Stage 2 for only $100 more, this will get my ready for down pipes in the summer.

That sucks man. I'm glad no damage was done and I would definitely go to the stage 2 for just $100 extra bucks. What did your stage 1 put down?

The Service Campaign ECU update was recently done to our vehicle too.

It doesn't have a "tune": after the update it seems like the vehicle has more accleration now.

never got it on the dyno

but OE is usually a bit more conservative on their tunes which is a good thing. I would say 460RWHP to 470RWHP and about 520 to 540 RWTQ on probably dyno jet.

The down pipes will probably get the numbers to 500RWHP or so.

At this point, I think the car is really not engineer to handle more power and torque.. the suspension set up is too soft and the open diff is not ideal for that much torque.

The AMG cars are usually better putting the power down, the ESP calibration is much better and smoother.

On this car ESP is more intrusive than my previous AMGs.

That's a nice power upgrade.

I'm in the same position as you are. Dealer just flashed the car back to stock from stage 1.
Looking forward to your input on how stage 2 compare to stage1 with stock dp and exhaust.
