does it sound like its struggling to idle? Maybe your fuel mixture is messed up. Does it ever kill?

when your "giving it gas" are you putting the pedal to the floor?

My last motor sounded like a v8 with a cam at idle. Boost guage bounced at idle like it had a large streetport. It was broken apex seals. I guess I should have asked you if the motor is heavily ported?
