Im having trouble with my boost or gauge im not sure which it is. I cant seem to get a consistant reading from two different boost gauges. IT reads any where from 1.1 - 1.7 bar. On one of the gauges it reads that im pulling more than 30lbs of vacume. One min the boost is holding , and another min its tapering or spiking badly. Im using a turbosmart mbc and bov, and dynoflash. The controller is hooked up in between the bov and intake. The two gauges i am using is the blitz blm reading in bar and my old ractive gauge reading in lbs. Ive put both gauges on different lines thinkin my original line was pinched. The car hasnt hit fuel cut or anything like that but its felt slugish at times. I was thinking boost leak at first but why would the vacume show 30lbs + at idle. Ive searched a thousand posts looking for answers but i havent seen any thing quite like my problem.
