1st World Problem...lol
Ever since I got my tune, my 550's sunroof inner cover panel slides open under heavy acceleration... 
Does anyone know if there are felt strips or something that can be replaced in the roof/headliner assembly to help correct this issue? Konigstar, you got a breakdown?

Yeah, didn't do it till I got the tune, but it has gotten worse. I'm sure it would do it at stock power level now as well. Slides all the way open now, especially on a decent launch.

That is one thing I miss about my E550. Even without a tune, the lurch from the NA V8 with 4matic would open the moonroof panel a couple of inches every time. You get used to it.
