Just curious to see what the new 550i's are putting to the ground. If you have dyno'd one, please tell us what type of dyno was used, Mustang/Dynojet etc..

Mine is the "Only" one privately bought in the UK to date, mine has covered 1450 miles and is still not yet run in properly, so it has not been Dynoed.
I may get it done sometime in the future but it is very powerful STD so remapping is not really required IMO. Time will tell though.

Looks like BMW under reported the output of another TT engine. The numbers are impressive indeed. Too bad it wasn't available for the e60.

Many thanks for the info, The engine obviously makes the advertised power and some, great news, mine just flys in any gear.

Nice find, thanks! 390whp and 435tq is a lot of power outta the box. These things will be monsters when tuned. I guess they dont have a choice given the curb weight.
