I also agree on the SVS fellas. I met one of them at Autobahn Country club last year, he had a turbo viper he was testing, too bad it started raining. Real approachable guy, friendly, and gave me his card. I seem to hear nothing but great things about them, and they work on plenty of vipers and have experience I would imagine. Fall Line Motorsports is also another person to consider, they do a lot of great stuff race stuff. Ask for "JP" tell him your a friend of Naz. I believe their website is fall-linemotorsports.com, but try to google it.
