Just installed Sprint Booster!
 

My co-worker told me about sprint booster when he was complaining about his Audi A6 being sluggish and wanted to try it. He bought it for almost $300 and was very happy with it.

I was looking around on Ebay and found one last week, used with no reserve... long story short i won it for $14 haha :D My Co-worker was pissed!!
Even though it was for a 3 series it bolted right up, the guy from sprint said all the BMW's were the same, not sure why they have different part numbers but anywho..

I gotta say, this thing makes a big difference on how the X5 drives. No more sluggish pickup, you have the power available right away. I turned if off and on bunch of times to make sure i was feeling a difference and oh man, im stoked! You can have it off, one press gets you to green which is still a good improvement, second touch is red which is all out. I'll be keeping it in red.

The highway driving is sooo much better now, overtaking cars is a breeze. I will recommend this for sure. The fact that i got it for $14 is even better :)

I am assuming this is like a sport button....I added a similar feature to my 530xi from roskinc which activated "Sport Mode" and tightened up the suspension and steering in the car. Totally changed the dynamic of how the car reacted and felt. Was thinking of changing out the shifter to get the sport function but this seems a bit easier and cheaper.

This is just for the delayed throttle response. Basically your cars power is made available to you the second you want it versus the delay you get, especially noticed on the highway.

OP, what model and engine do you have?

2011 x5 diesel. I was told by the guys at sprint that all the bmw ones are the same. This one was for 3 series but i took a chance in hopes of making it work and turned out it plugged right in.

Some people say that DDE adapts itself again after a while and throttle response gets back to normal.So please monitor it and see if there is any truth in that statement.

Will do! You can always reset it, which i have done before after every few fill ups.

Have it on mine 4.8i it does make a different

I can't believe people fall for this. SB does nothing more than you could do yourself by pressing the accelerator harder or faster!

I guess $14 isn't much to spend though :-)

Not true, i though that way too until now. You touch the throttle and bam! I turn it off and floor it, it takes good 2-3 seconds before it downshifts and starts going.
I don't think i would have paid almost 300 for it, I'd get the JBD but yeah, for the price i got it for its definitely worth it.
