Wow... I would love to see what would happen if you said "Shiv at TurboXS" within earshot of him!
I used to work for him, he owns his owned business called Vishnu Performance Systems in Fremont.
Nate is the tuner at Subaru Specialists. He used to be the proprietor of S-Squared before merging with Alfas & Subarus to form Subaru Specialists. He's the real reason you don't need to go see Shiv. EcuTek tunes by Nate are $650 for standard and $750 for drive-by-wire cars I believe. I absolutely recommend having Nate tune your car. Almost everybody on this board has, and you'd have a pretty hard time getting anyone to say something negative about his work, and more importantly, his customer service.
