Anybody install Dinan Stage II for X5 35i?

Has anybody installed Dinans Stage II software for their 2011-2012 X5 35i? Looks impressive, HP increases to 355 and torque is 401. The torque is in diesel territory.

I'm interested along with the JB tuner.

The reason I asked was that with this tune, fully backed by Dinan warranty, the 8-speed gasser suddenly looks very attractive compared to the stock 6-speed 35d. More HP, almost the same torque and all the benefits of having a gas engine versus a diesel (hope I don't start another gas-diesel argument...). If the final vehicle price would be similar to the stock diesel, I would probably go with the gas engine even with the better mpg of the diesel.

Comparing a flashed gas to a stock diesel seems faulty.... you should be comparing it to a modded diesel.

Of course, Dinan doesnt offer a diesel tune (yet) but others do.

Same argument can be said about N/A engine versus and Turbo, superchargers....

Ard, I realize that it isn't fair to compare the modded gas engine to a stock diesel. My point was that with the Dinan tune, the 35i has now closed the performance gap with the stock diesel.

Close the performance gap?

I believe he means in regards to torque.

And my point it that when you flash the diesel, the 'performance gap' is right back to what it was, or more.

Arguably a Dinan tune is different than the tunes available for the diesel....in terms of non-performance attributes...

About the Dinan warranty, what happens if you go to BMW to service your car?

It is a very common misconception but BMW won't warranty the drivetrain with this tune, so Dinan does for the full 4x50K to match BMW.

Yep, that's what I meant. The available torque on the X5 diesel, along with the better mileage, was what sold us on the diesel when we were shopping back in late 2009.

Diesel is quite sluggish compared to the X5 35i, stock compared to stock.... so there is a big performance gap. 35i 0-60 is 6.4 secs and 35d is 7.2 secs. The diesel gets only 3 mpg better fuel economy. Plus, diesel fuel, at least currently, where I live is 30-40 cents more a gallon than premium unleaded. To me the X5 35i is a no brainer over the 35d. Adding Dinan Stage 2 for the same total cost as a stock diesel is just gravy! I expected much better from a BMW diesel than this.

here we go.......again

Just remember 1 post, 1 post, 1 post

I like diesels but if I had a gasser 35i already and wanted more performance then for sure I would be looking at the Dinan tune. The only thing that would hold me back would be the CARB problem -- ie: is it legal in Ca? OTOH if I had a diesel already, and I wanted a tune for that -- would that mod be legal here as well? The real comparo, at least in my mind is the choice between the 50i and 35i gassers. With the 35i tune the two performance envelopes seem pretty well matched. Of course, with the V8 you can get a tune that boosts it even further up too. In any case it is nice that there are some options out there.
