What do we know about the z1 lower intake manifold?

Yeah I reinstalled just the stock upper plenum and left the port lower manifold on. I did a before Dyno where I reset the ecu then did a run with the Z1 parts. Then we changes out the upper plenum and reset the ecu while the car was on the Dyno and did another run. I gained 5 horsepower going back to stock. So this weekend I'll do the same with the lower intake manifold. I've been speaking with Z1 who has been very helpful. Once I change the part out I'll let them know what I find. We are trying to determine if there's an issue with the plenum or something else on the car. I will keep everyone updated. I'm not in anyway speaking badly of Z1. They have been very helpful to me. Things happen and I'm not total sure it's an issue with there part yet. I just wanted to keep the community updated.
