Custom intake manifold poll! What will you pay

EzDz

Ill be dropping my car off in the near future and itll stay with them through winter. I told them what mods the z crowd has and what hp we would like to see, we were talking throttle body and running double tb's they dont think they will need upgraded and will not bottleneck the manifold. After they get mine in they will get the manifold mapped out and on a computer program with the engineer and see how everything will flow. I was promised if the tb's need to be bigger they will be, but keeping them stock size will increase the velocity of the air coming in.
