I am new to Cobra's and am looking at an 04 we traded for(I work at a local ford dealer). When you mat this car it will instantly peg the boost gauge and one it does it drops down to zero. If you part throttle it, it will hold 7 pounds or so. It does look to be pullied cai and no cats ( I have no idea what size pulley though). The car still pulls hard but the boost issue concerns me a little. Is this common or does this car have some sort of blow off valve that I am hitting. I am looking to do a few mods as I want to hit around 525-550 rwhp but I need to read up more. Thanks in advance for the help!
