How to avoid the double hump in torque often seen in dyno output? Considering a 5.7 with stock 241 heads(and LS6 intake) and typical street exhaust.
Notice the double hump in torque first peak and then a trough and then the peak as the intake forces torque at 4800rpm.
Is this a result of tuning? exhaust type? wave harmonics? Or camshaft timing as in too much overlap?
What I am getting it that I would rather tradeoff a few upper end hp and not have the depression occuring after the first peak in torque.
