FS: Cobalt-Addiction Stage 4 Upgrade Kit
It could be very close to 300 with a ported blower and Intake manifold. After I ported the blower and intake It pulled like mad all the way to 7k. Keep in mind cooling mods also greatly help the performance of this kit.
You guys are aware that the PCM is vin-coded, meaning that it won't just come out of one car and go into another. You will have to have someone with HP tuners change the VIN for you.
