Daneo 330 Member 14 Member For: 15y 3m 14d Posted 01/10/09 01:28 AM Share Posted 01/10/09 01:28 AM Hey guys this is probably a fairly talked about thing but I was wondering if anyone could explain to me, I just installed boost and oil pressure gauges in the dash cluster and took her out for a strap, My boost gauge is connected into the BOV line and only reads 11psi and about -10 - -15 Vac, when I put my car on the dyno a few months ago it said that my Manifold pressure was reading 15psi @299rwkw... is my boost gauge not reading right orrr is there an explanation for this????
