N55 vacuum low

TripleD2047 · 03-15-2019, 05:10 AM

Hello everyone, new to this scene here. I have a 2011 335I n55 equipped with stage 2ppk & MHD stage 2 tune. I have a VRSF catless downpipe, drop in dry intake filter & muffler delete. I use an obdII link to monitor gauges & my vacuum reading is always very low. I've never seen it -4lbs & usually it is -2lbs if I'm in gear decelerating downhill. It fluctuates from about -1lb to 0 unless I get on it& start boost. Is this normal? What is a normal reading?
