Dyno tuning & 4L60E W/TCI stall converter

[Night Move]

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?

Probably shoulda called TCI to start with.

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.
