[335nwb]

Hello
I'm new to tuning/car stuff.. got no experience at all
but I'm getting a 335 and really got interested in vishnu and would like to order it but I got few questions that I couldn't find answers to.. or maybe there were answers but I might be too noob to understand them
Anyways.. I'm from Kuwait (ME) and wondering if I can order it normally like any other product I online (I do order lotta of stuff online and do have a US box)? and does it violate/break the car's warranty? and do you guys think I can find someone to install it here?and which should I get stage 0 or stage 1? and are there different versions? kinda lost lol.
Your simple answers, and general advices regarding my situation are much appreciated.
