Where a bouts are you in the gulf? I'm in Qatar and the Evo X here is EDM spec so should work fine, but just double check with the dealership as they will know for sure.
As for boost control the stock system will easily cope with just map upgrades and exhaust etc, when you are going to go for a bigger turbo and want 30psi or more then I would start to think about upgrading, also there is a restrictor pill that has to be removed when you are running Cobb stage 2 there is a PDF file on their site on how to do this.
Hope this helps a little...
