Hello all. I have a 05 ctsv ls6 with a Maggie. I need to pull the supercharger off to replace the knock sensor.I just had it dynotuneded last week and as soon as I left the mil light came on.The car runs flat. I am hoping that this will get it perked up since it isn't advancing the timing.( assuming this )
Any tips on removing the super charger? Would be much appreciated! I'm an older guy and haven't messed with these new engines very much. Thanks. Lathedog
