It was brought to my attention that even though the stock manifold is not properly balanced, that the stock tuning and timing allocates for that imbalance (well partially anyway). I guess my question is, will the stock tuning run a greater risk on the balanced intake manifold, by leaning out cylinders 2 and 3 because they are now allowing more air into the system?

Am I looking at this all wrong?
Grimmspeed does not longer offer services for GenCoupe as i remember. In case yours is not already done. The other choice now is MAPerformance, which seem like more deep upgrade, but more expensive. In fact they cut manifolds open to port/polish better.
