Diablo72887 Posted June 7, 2008 Report Share Posted June 7, 2008 I am thinking of doing some mods to my SGT and wanted to get some opinions from you guys who have these mods or are knowledgeable about them. I definitely want to increase the performance of my SGT but want to retain as much as the warranty as possible, and not damage my cars internals over the long term. The mods I was considering were the Steeda underdrive pulleys, a professional dino retune by Galpin Auto Sports, JBA shorty headers and/or 3.73 gears. Any insight into any of there options are much appreciated. Thanks A.J. Link to comment Share on other sites More sharing options...
