Take a look at the Dinan warranty statement here:

Dinan BMW - Warranty

Dinan is conservative in their hp increases. They sell and service through BMW dealers. They cover consequential damage. For all of these reasons, they are much more expensive ($/hp) than other chip tuners who will sell you the same hp increase for several hundred dollars.

There is always a risk of falling between the cracks of the Dinan warranty and any potential BMW warranty refusal. That is why I suggested working with one dealer, preferably one you have a relationshipo with, who can help to bridge those potential gaps.

Or you could wait and buy the performance software kit directly from BMW.
