Yep Turboranger91 is right you won't build boost sitting still. You have to put a load on the motor. Then boost should come up. If still no boost sounds like you have a plugged exhaust or cat. Also check your tps to make sure it is set correctly that can also effect idle.
Flyin with the bird's or runnin with the cat's either is better than ridin horses!
