Ok so i have been up reading on the installation of the greddy profec b for about 3 hours I think i have some grasp of what im doing I thought the install options were interesting [im going with version 1] but after reading up on the settings [holy ****] looks like i better be careful!!!! i guess i can forget running 14 to 15 of boost my mods consist of greddy smic,blitz intake, pettit down pipe, pettit resonated midpipe, peter ferrel cat back pettit unlimited ecu, greddy elbow,hard pipes efini y pipe along with a bunch of other **** not related to engine performance . So anyone have any settings as far as boost levels i should be concidering its hot as **** im fla now so im sure ill have issues with consistant performance. Throw me some bones [tips] if you have any imput DO I NEED A BOOST CONTROLLER TO EVEN GET WHAT I WANT OUT OF MY MODS EXAMPLE THE PETTIT ECU] thanks Greg
