Next weekend is Bimmerfest at Auto Club Speedway in Fontana:
BMW Event: Bimmerfest 2016 California Sponsored by ESS Tuning on May 28th, 2016
I plan to make a few laps on the track to test my beast to it's limits. I know X5M's are wickedly fast around tracks with their proper brakes and torque vectoring, but didnt see heard of any other X5 seriously driven on the track.
Whomever is interested in chat and ride along is welcome to stop by and say hello.

I decided to go Saturday and had no regrets.
The car is completely stock (lol, except the engine) with almost full tank, spare tire and some tools in the trunk. With me inside it must be sitting at around 5,700 lbs. This is Speed ventures Red Group, open passing, dedicated track cars and very experienced drivers.
In the morning it ran great getting to 126 mph in the early laps, but after the air warmed-up the power dropped. I am still running the stock intercooler, which is Ok for stock power, but insufficient by large margin for the power I am running at. The brakes started to fade after 6-7 laps, which is amazing considering the speeds and the weight of this tank. There were 2-3 seconds to be found without changes, but the idea was not to take chances, just to have some fun and prove a concept. Yeah, i dare guys with Fords, Acuras, etc to try this ;)
Oh, and it does 7-8 Mpg around the track :rofl:

126mph! That's pretty quick. I'm pretty impressed by the braking performance as well. Six or seven laps before fading is amazing, as you say, for a tank that is the X5.

And pulls 1G lateral in a stock form :yikes:

Hi everyone. Here's a quick review of DPF/EGR/SCR Delete.
Entire process took me few weeks but that's only because I used the car on daily after dde flash. Nevertheless, after dpf and. Egr were removed all I can say is wow! What a difference.... Its like driving brand new car. Turbo sounds awesome, throttle became crisp and responsive. Very very impressed with results!

Thanks to Bawareca for dde work and my buddies who helped to remove emission crap. Also, it's not a kind of job that can be done in the garage. Professional shop with proper equipment is highly recommended.

For those who wonder what EGR looks like after 118K miles with 3-4k miles oil change see below:

My CPO warranty expires next month so I'll very interested in doing the delete and getting the tune. Just have to figure out how to pass CA emissions which is my biggest concern.

TRF Performance X5 35D Stage 1 flash tune
 

Friend of mine who works as mechanic at Paul Miller BMW of Wayne replaced temperature sensor for me yesterday. He said that over the past few years so many diesel cars experienced problems with emission regulatory equipment that now they keep in stock bunch of parts such as active/passive tanks, sensors and etc. They all surprised that recall hasn't been issued. Nevertheless, I am very pleased with the path I went. Instead of replacing damn def tanks and spending tons of money I decided to do it once and for all. Anyone who has questions during the removal process feel free to ask, but I'm sure there are plenty of info on this matter. Results will pleasantly surprise you. Btw, my mpg is 26.7 vs 19 prior the tune.

So what exactly was your path?

Stage 2 tune with hardware delete vs keep replacing faulty oem parts...

Your avg speed was 64mph so almost all highway looks like.
I get close to 29 mpg in similar situation. 29.6 mpg i got once on full tank, all highway driving. Im sure it helps with mileage but 26.7 seems normal for me.
2011 x5d is what i have with 117k miles
