What is Cruze plastic intake manifold porting? Is it the removal of the small "dam" at the point the intake attaches to the head? Does removing this "dam" make more power? Does it make less power? Does it make more or less low end torque? I have the head off putting in new pistons, so it would be easy to do now, IF, it would help.
We are making 249 HP @ 7400 and 206 # @ 4700 with HEP turbo upgrade and Trifecta tune.
