    I recently witnessed a Jeep Wrangler with a 6.0L engine and transmission transplant from a 2500 truck pick up 97 ft/lbs of torque after tuning. Timing and fueling can be way off.

    Stock is...
    353hp@5400rpm
    373ft-lbs@4400rpm

    Assuming a very low drivetrain loss of 15%...you end up with 300rwhp. 53hp loss.

    After tuning...
    357hp
    382ft-lbs

    So assuming the same drivetrain loss, the flywheel hp is now 410hp? A gain of 57hp with only basic exhaust and CAI?

    I too would love to see the tune. Is it safe to say that engine is just tuned so conservatively from the factory? Should I be expecting to gain similar from my L92 with exhaust and cai?
