Ok, I get the reversion dam at part throttle situation. But at WOT I dont think there would be a lot of reversion pulses to worry about (isnt this the ram tuning for certain rpm that mopar played with). Thats why I questioned the tunnel ram and search for more "tourqe" instead of peak #. you dont see max wedge heads using standard size manifolds. (I know that is an extreme example)
I would also be concerned that the mismatch isnt consistant on all runners, so if its good or bad it wont be the same every where for sure.
Its always fun Questioning you Cab!!
