I just finished my intake & rocker install. I had a few issues with getting a base tune set up for the new 42 lb injectors & thought I would also hook up my vacuum gage just to see what it had. I have a 308 with the F303 cam & 1.72 roller rockers. With the new rockers the cam now has 2* over lap at 0.05lift. Would it be normal for the eng to idle at 13"HG or is that a little low? I havent tried to search for vacuum leaks as I didnt have any starter fluid at the house to spray around. I will probably pick up a can this weekend just to check it out anyway but, I was wondering if you guys have seen this before & it is normal? it has enough vac to pull the BOV open when I reved it so if its normal I wont be to concerned with the low vac. Thanks in advance.
