Thanks for the reply. I certainly agree with you in that the numbers being posted by the 335's can obviously handle the horsepower and torque increases but the chassis is a completely different set up with lower centers of gravity and much different horsepower to weight ratio which seem to be more true to race inspired cars. Take for example as I posted earlier in regards to my boat mechanic"s duramax diesel in his chevy it produces enormous amounts of torque in which I seriously doubt chevy prepared for. On the highway his truck can embarass quite a few sports cars I think due to the immense torque which is created via the large single turbo spooling at a different rate. Since the weight of his truck is extremely different than that of a sports car, the heavier truck responds well to the remap and creates a better horsepower to weight ratio to more efficiently increase performance and keep normal fuel flow when not being abused. In reference to the tow capability I was showing the present X5 with 4000 lbs of added weight, can still brake impressively. I am not completely versed in how that compares to a 335 under extreme acceleration which has been remapped and needs big brake upgrades. Just trying to compare apples to apples. Bottom line I think the X5 can handle the increases but the real deal is BMW USA cant handle it.

BMW even has service bulletins on aftermarket tuners on the boosted motors, and are incorporating more detection for it all the time. When I get home for lunch and have more time I can look up the bulletins for ya.

Hey Boz,
do you have this on your vehicle?
Weasel all info much appreciated.

During the development of the 6 series, BMW did a documentary on it's design and development as it moved from a paper concept to a real car. It must be gratifying to any BMW owner to see what goes into the design and manufacture of their car. And alot goes into it. It is not like they grab a bunch of parts and bolt them together, slap some body panels on and voila a car is born.

If you are not a BMW engineer, I don't know if you are really qualified to offer a reliable opinion on what a BMW can "handle" and what it can't. There are a few factors to consider: Will the car as set up be able to safely handle the power? Will it be safe at new limits of speed and cornering? If the car goes to 60 in 4.5 instead of 7.0secs, is there enough braking power and rubber to haul the car down in a safe distance?

And then there is longevity. I wonder how many people buying a BMW are looking at it's longevity measured in months vs years. Even if safety doesn't concern you, longevity should unless you lease for 3 years and dump the vehicle. If you plan on driving your X5 for 4 - 6 years, maybe you'll find that you've paid a pretty high price for more HP and torque.

Even BMW has miscalculated in the past. Examples are the last generation M3 engines (warranties extended to cover problems after high revving), BMW's hesitation in installing a manual in the M5 due to durability of that transmission when mated to a 500Hp engine, cooling problems with early 335's.

Personally I'd be sticking with performance improvements from Dinan or some other company that has worked with BMW to provide a performance "fit" that can meet the needs of the enthusiast, while at the same time not creating component failure or a safety risk.

I will have to look it up at work, for some reason I'm getting a server error when clicking on the bulletin when trying to see it from home. (the website is very picky about windows/internet explorer, java versions, etc.)

Not yet but I am like you, very close to making a decision. its either the BlueFin unit or having something similar done by the local DMS agent.

Hey Bozz,
Let me know which unit your leaning towards and your reasoning. I always seem to buy vehicles that are so new that I become the guinea pig. Also heading over to Brisbane in the near future (noosa head) to be exact have some good friends there. How do you like living there?

Printed out the bulletin at work... then forgot the pages in my toolbox.

But basically it said that if the DME detects altercation, especially to the MAF then it will limit the torque to 300nm to avoid drivetrain damage. (which I think is strange due to the fact the 335 has no MAF sensor...)

If I remember I will bring it home and scan it.
