Wanted some conservative power gain on the Cobra while still making it reliable for daily driver. So had Shaun at Advance Engine Development installed a 2.93 billet flow pulley and 100mm idler combo with an SCT X3 tuner and NGK TR6 plugs. Dyno SAE chart showed 433horses and 438torque. Pretty happy really felt the torque nailing you to your seat! Thanks again Shaun! :beer:
