I noticed that the sc doesn't start to make boost until about 2500 rpm and it is at full boost or pulls hardest at 3500 or 4000 rpm until redline. Any time before 2500 rpm the car seems to bog (sp) down. Is this my car or is that normal. My car is a 06.

 

It would be normal for it to have low boost when at WOT and low rpms, but not none at all. Even at 500-750 rpms (at 500 it's boosting to try to get itself up to idle speed) I get a couple pounds. You won't see higher boost until around 2500, at that point you should have at least 5+ pounds, I think.

 

The SC does make boot just not max till higher revs. Like bredick said it give more and more boost as the rpm gose higher.
