Really? That's weird - can you explain the technical reasons why?

I was under the impression that the longer runners shifted the resonant characteristics of the intake so there were stronger pulses earlier in the rev band (making a slightly more use-able torque band), I'd like to know why and E85 tune changes that effect. Maybe has something to do with cam timing?
