    Dyno tuning & 4L60E W/TCI stall converter

    How reliable are the numbers im getting. Mild build & Blown 5.3L 469.5 HP/449 Torque @ RW

    1st considering it's hard to get up power & RPM with out down shifting out of drive. 2nd in theory the converter is not locked up while making a pull (although something does happen @ about 5,800 because power & torque abruptly drops off @ that point then levels off) @ 5,800 torque is falling but HP is headed toward about 500 @ 6,000 when it abruptly drops.

    Any ideas out there?

    first off I'm no pro.
    if you are using hptuners, you should beable to go into RTT (real time tuning)- transmission setting and make your converter lock and force it to stay in the gear you want

    You should be running it in 3rd on the dyno, that is 1:1 ratio of the tranny.
