I was just wondering what kind of vacuum levels I should be showing at idle on a stock LS Vtec motor. According to my boost gauge I am only at 11" of vacuum. I've read around a bit and it seems really low. So do I have a boost leak somewhere? And am I losing a significant amount of power from this?

Here is my setup
Stock B18A1 Block/ Stock B16A Head
BWR Ramhorn
38mm Tial Waste- 8lb spring
Garrett GT35R
Edelbrock Victor X IM
70mm TB
3" IC Piping all around
Mishimoto FMIC
Exhaust and Wastegate both are hood dumped

 

Should be in the -20 -24 area with your engine @ idle

 

So im guessing vacuum/boost leak somewhere
