[QUOTE="JimIII@jdm, post: 13144814, member: 10902"] Austin, Sounds like you would really benefit from our [URL="http://www.teamjdm.com/2007-2012-shelby-gt500-750hp-tvs-supercharger-upgrade/"]750 HP package[/URL] that we offer. It includes the TVS blower kit with Mono Blade TB, bigger fuel injectors, and the JLT air kit! Everything you need packaged at a great price.
