I had read that people have drilled and tapped the intake manifold. At this point in almost April I have no desire to pull the intake manifold off of a brand spanking new engine and drill and tap it. Not looking for any more “big” projects I understand what you are saying but I’m not trying to open up any can-of-worms type scenarios at this point. Just hoping to drive and enjoy the car and do little projects along the way
Initial timing is 17 deg. The tuner I am using sent me the revised base tune and I hope to load it and test drive the car tonight. I mentioned the vacuum to him and he said it will change as he makes tuning changes
