Dinan Stage 1 Software Upgrade for 550i

I've got a new F10 550i and am, to say the least, intrigued by Dinan's Stage 1 software upgrade. (http://dinancars.com/shop/D900-44T5-...de.aspx#page=1) 495-hp, 573 lb-ft of torque -- nuff said! :-)

A few questions for the group:

1. If you've gotten the upgrade, how satisfied have you been with it?

2. I live in California where, apparently, this is not street-legal. Have any California denizens had luck getting it for their cars anyway? And if so, are there any issues with passing smog?

3. I have the 6-year, extended factory warranty (i.e., a longer period than Dinan will cover). Any issues with getting repairs done under warranty with this upgrade?

4. What sort of decrease in engine life can I expect?

Many thanks in advance!
