Lateset and greatest FSP tune from Eurocharged review
https://mbworld.org/forums/w211-amg/...fsp-video.html
Hopefully somebody can get in contact with Eurocharged so they maybe can adjust the flap juuuust a little so it gets milder during idle.
That is great to hear for you guys with this FSP and for others wanting to get it. I don't mind the small delay (I have the factory upper pulley and mine seems to be a very very slight delay) but to add to the plus of this pulley, I drove to Florida a few months ago and average exactly 20mpg! I have a few mods as well so it seems that it doesn't affect mpg's on the highway.
