hey guys i have an 04 LB7 duramax, i'm putting a boost gauge on it because the edge cts only reads to 24 psi. Will it still give me an accurate reading it i T into the boost line that is on the turbo? or should i drill and tap into intake manifold? i would prefere to just T into that line since it will be easier and less messy. But which will be more accurate? thanks
