Default Boost or lack there of.

My procharged camaro isn't making boost any more. Everything is hooked up correctly and I can't find any vacuum leaks to the bypass valve. Any ideas what to check next?

Belt is tight and new. My boost gauge goes right up to 0 quickly then doesn't move. I can hear the supercharger over the engine but I don't feel any boost like it used too. Everything is hooked up correctly and I couldn't find any vacuum leaks or cracked parts that leak. I am out of ideas for now.

Some details on history prior to this "problem" occurring would help.

Or are you trying to suggest you suddenly jumped in and drove it one day and it had no boost ?

I left the car in the garage since we had lots of snow. Now when I took it out and got on it no boost. Nothing has changed on the car since I parked it.

Tomorrow I am going to go through and look at all of the vacuum lines and clamps again just in case I missed something. I am hoping that it is something simple and stupid. Not that I ever miss anything ever.

Something you should check if you have an older ls1 manifold with egr port make sure its not leaking At all. I went most of last summer trying to figure out why i wasn't making boost until i finally pressure tested everything and it was pissing out my block off plate like crazy.

Good idea since I have an ls6 with a capped off egr port. I never would have thought about that.

I just went out and tightened the plug and it was actually loose. I hope that it will be something that easy. I haven't messed with that plug since 2002 when I put the ls6 intake on.

Car show was alright but no new corvette, no Porshce caymans. Mini was there but no bmw. The Army display was actually one of the bigger displays.
