This is for XI owners who have had their cars dyno'd. I called a shop in the Chicago area, "Chicago Performance (http://chicagoperformanceandtuning.com/dyno.php)," in regards to a dyno for my E90 335xi.

Looks like they are pretty experienced with European AWD vehicles, however, when I talked to a tech he mentioned that AWD vehicles are more difficult to dyno than RWD cars.

He mentioned that the car might need to be placed in a dyno mode (both DSC and DCT off?), that the dyno itself has several different modes, and that the type of dyno machine is important.

I was wondering, for those of you with XIs that have dyno'd their vehicles, what was your experience?

What type of dyno was used?
Were they're any special preparations?
Did you run into any problems or snags?
I'm running a 19x8.5 and 19x9.5 staggered setup. Would this cause any problems?
etc.

Also, if you have any suggestions of AWD dyno locations near downtown Chicago please let me know!

Thanks for your help!
