Stage 2+ K03 Vacuum & Boost
« on: November 03, 2019, 05:34:41 PM »
Hi all, first post here - i am running APR Stage 2+ on a BWA engine currently and have just installed a boost gauge, i am seeing -20hg vacuum at idle when warm and -22 when coasting in gear off the throttle, boost spikes to 19/20psi in 4th gear at 2500rpm, is this correct or do i have any leaks? my long term fuel trim is 0% - trying to judge whether to go and get it pressure tested but first want to know if my numbers are quite normal  :smiley:
