I'm just here to pass along what I think is good info to fellow members!
Dealer did not comp me for parts and labor and I spent a lot of time going to get it dyno'd.
A member asked if I would pull the charcoal filter and dyno after plates were installed.
I knew my car was running slow during a run we did at high elevation in the canyons as I would have to downshift early to keep the speed up. My shop open up the air box as I wanted to see the charcoal filter and we discovered the holes which he said was strange.
He got in another M5 few weeks later and took picture of the sealed box which I sent to dealer. Overall I'm happy with how the car is running so now just waiting for the right tune.
If you have doubts i suggest you do your own dyno. I'm not here to sell you anything...just sharing my own info
