I had the intake scoops for my old 545i and they really made a noticable difference. The process will probably take around a month so I wanted to see if there is anyone with an X6///M that is really interested in these products. I will post pics and dyno charts as soon as everything is completed. I am really excited about the gains that will come from their products. The chip may be upwards of about 90-100 hp gain, 10-20 hp for the intake scoops, and I am not sure about the exhaust. Post replies if you're interested! |
Congrats David
can't wait to see the dyno numbers! don't forget the sound clips too!

But, you had better have the fuel curve mapped exactly to avoid detonation with these high boost levels. This is a trial and error process to be sure, and you risk some damage in the process.
There is the warranty issue also. The warranty on your vehicle is barely a few months old. It is sure to be voided by any modifications, so I would think very carefully about why you want to do this. What if BMW improves the vehicle in the next few years such as with the 8 speed transmission, you would like to trade it in for an upgrade, and no dealer will touch it because it has been modified?
Of course, if it is chump change, then by all means, go for the gusto!!!

I would be curious to see the pics so I can see the scoops and how they are placed.

I've had extensive mods on my 535i (n54 engine) and have just about all the bolt on mods available on my M5. I have never had any warranty issues whatsoever at the dealership, with either vehicles. The only way your warranty will be voided is if they can prove the issues are directly related to the mod.
the only thing i've heard from the dealerships are nothing but compliments!
