Doing some work on my brakes.
I have a 224/230 cam and I am wondering if I really need an aux. brake vacuum canister. The MAP reading I get on my Datamaster is 17 points. IIRC the stock cam was 12 points. So with BAR at 30 points clearly my aftermarket cam does not provide the same vacuum, but is it really a concern. I never really noticed any difference when I put the cannister on.
Can anyone say without a doubt, I dont need a cannister with my cam?
