Welcome Yimmy85! Welcome to San Diego, rough weather lately but you will enjoy the stay when mid-Spring, Summer, and Fall hits. Towns to keep in mind that are heavily filled with tuners: Mira Mesa (my town), Kearny Mesa (my 2nd town, use to live there as a kid), San Marcos, Murrietta, Temecula, Chula Vista. Miramar Road and Sorrento Valley are both in Mira Mesa but I do not know about their shops (doubt there is one in Sorrento Valley, it's filled with a bunch of white collared businesses). My friend, whom is a HIGHLY skillful tuner, can assist you with all your needs. This guy has been working with cars for 30 years, specializing in Japanese. He's done it all and STILL DOES IT! Very trustworthy guy, lives down my street and glad I met him. He speaks before I do any type of modification or purchase of a car item/car. Any questions or concerns, let me know with a PM (Private Message). Enjoy.
