No I haven't had a chance to work on the car. It's been mine and my little brothers birthday so it was a bit of a celebration this weekend. The Z1 lower is still on with a stock plenum. I have a friend who is about to sell his older Z1 plenum, so I'm going to barrow his and swap it on and see what happens. If I make more power with it then we have an isolated incident with my current plenum. If I lose power again it will call into question if any of the plenums make power. I'm also hoping to change out the lower manifold but after holding a stock one in my hand and the one from Z1 in my hands I doubt there is much of a difference.
