More Zoom?

So I just purchased a 2015 X1 with the M Package. Super nice ride. Problem is, I test drove a 3 series before the X, and it was so much quicker.

Is it possible to get near 3 series performance from the X1?

Provided you are correctly matching models (28i vs 28i and 35i vs 35i) the performance should be pretty close.

I'm guessing you drove a 335i and ended up buying an X1 28i if you feel there is a big difference. There are certainly options to increase the performance of the X1, but I'll let others chime in since I haven't done any on mine.

Likely. After a little research I found that Dina makes a CPU upgrade that supposedly gets it to 355 hp and 401 torque.

Anyone have any experience with this? Is it legit?

Dinan is rather expensive, check out JB4 - similar gains but far less expensive. Just make sure you're looking at the correct engine for the performance gains: 28i is N20 or N26 engine whereas the 35i is N55 engine. Check what car you've got.

I haven't done either upgrades in mine either so I can't comment on the power gains, but I have read from a lot of happy people on the forum with these.

Good call. I was looking at the tuning software for the 35i. I can still get 300 hp for about $1500.

My concern with non Dinan is that it's likely to void my warranty.

Read up on it, there are lots of threads, especially if you start looking at the E90 forums.

Most people use JB4 software... it's quite reliable too
you get more HP out of the turbo

I have the jb4 on my x1 35i msport and it is a rocket. I outrun my Porsche boxster.
BMW does not warrant a Dinan tune. Dinan does.

I also have a JB4 on my 35i non-msport and must agree, it is a rocket. Eventually looking to do chargepipe and downpipe, go to map 2 or 5 (possibly 2 in summers and 5 winters, Florida heat/humidity is a beast). I'm looking into the ISO firmware, but that is a ways out due to worky.
