Let me know how it goes because as I now think about it, I didn't get the red envelope, either. I did get the 3 stickers/plaques...and a receipt. I may call the dealer tomorrow and ask them to look in their system and make sure it's noted under my VIN.
I definitely can feel the difference, so not too worried, but always nice to have backup if I go sell the car. The dyno doesn't hurt either...torque jumped from 308 to 333 at the wheels, you feel it.
