    "As much" was the key phrase.

    Pretty safe to say all LS motors make torque through the powerband.
    How much VS the same engine with the taller plenum truck intake is the comparison.

    On a side note I test drove another Denali with the LQ9 motor and I was more impressed with it's pickup.
    It might have had a tune though, never know.
