Not quite sure what you mean by vacuum mod but i'd stay out of boost until your car reaches operating temp. It could just be a seal that isn't completely sealing until it warms up and expands. Oil clearances in bearings are designed for operating temperature so when its cold things are tight and thats when you do the most wear.
