Boost gauge reading? Boost leak? AA Stage 2 E46

Hello,

I just noticed over the past few days of driving that my idle vacuum pressure seems to have changed from 20 inHg to about 22 inHg. I've also noticed it seems that I'm not quite hitting 12lb's of boost anymore, but more so 10lb's. Its hard to tell exactly because the car gets going so fast you don't want to look at the boost gauge.

I was wondering what your boost gauge reads at idle? Is your's about 20 at idle all the time?

I've noticed that my silicone hoses on my ITB's aren't sitting too perfectly anymore. Some of them seem lifted a little when I don't recall them being that way when I first installed.

I did have the manifold pop off once after install because the clamps weren't tight enough. I've ordered some T-bar clamps to replace the clamps that came with my AA kit.

It can also be the weather change. It has been getting a little more humid this past week. Depending on the time of the year I can go between 18-22 in vac.

My car is typically -12 but it's a twinscrew

Thanks guys I'm crossing my fingers it's ok!
