This shop did poor quality installation and tuning on my car. Had multiple failures which resulted in hundreds in tow charges. The tuning was terrible as it constantly stalled and lacked in power. Every time it went back more excuses on what it was and another bill for the repairs. After realizing they are incompetent, had to take the car elsewhere which cost me thousands to repair their mistakes. Zero rating!
