I'm in calif. So how & what can I do and not do to upgrade the car's performance?
For the 2007 R56 MINI Cooper S Hardtop, 'legal' upgrades in California are very limited.

You can get a CARB-approved intake upgrade like this K&N intake or NM intake.

Exhaust upgrades are currently safe as long as it is downstream from the cat and o2 sensors. (at least for 'today')

ECU upgrades are technically not legal in CA, but they are undetectable in the standard OBD emissions check....

The only turbo upgrade that is legal in CA is to install the factory JCW turbo on the Cooper S - small gains but it is a factory original part.

We have other turbo upgrades that use the same-as-factory K03 shell with upgraded internals..... but not 'technically' legal in CA

Any of the plumbing or intercooler upgrades are not CARB approved and will probably get flagged in the visual inspection...

I just purchased a 2010 JCW Mini Cooper S. I see you have upgrades for a Cooper S, but what about JCW? I think the suspension is certainly stiff enough but it would be nice if it were more supple. Also it could use more power and a longer power curve. Where do you suggest I get started?
Most of the upgrades for the Cooper S are also applicable to the JCW. Of course, the power gains will be slightly less for the JCW when compared to the Cooper S.

Improve the ride quality can be a challenge if you are not willing to give up some handling performance. Are you using run-flat tires?

For more power and a longer power curve, you might consider an ECU software upgrade, or perhaps a slightly larger turbo

An Intake upgrade will ad a few hp, but nothing near the items above...

We recently installed the G2NME2840R on our 2007 Cooper S JCW that has a stage 3 Alta tune plus a Helix stepped core IC, Alta 3" turbo-back exhaust. It had the dealer JCW kit installed originally and I believe that has a different intake. Now when I get on the throttle too much, it goes into limp mode. Could this be caused by the new higher-flowing turbo? It seems to cut out anytime you really want to get into it.
With those supporting modifications we don't see any issues with the higher flowing turbo - it would not cause a half-power light. There are several factors that could contribute to it, but having it diagnosed at a MINI-qualified service station would be the best place to start.

Does this have an off setting to pass CA smog check?
Sorry no, the software cannot be 'turned off'.
However, it is also undetectable based on today's California emission testing.

Happy Motoring
