Reaaallllyy.... Actaully you have 3 tuning states. But the diffrence between 8 degrees of seat duration especially on an oem application where ramp rates are slow for longevity It has the possibility of being worth 1 or 2 horsepower 2-3 ft lbs of torque difference. Cam timing plays very VERY little roll in intake manifold tuning. Thats all im going to say on the subject.
