48RE Torque Converter Lockup Tuning

I have adjusted lockup by 300rpms with hp tuning. Stock tune would lock converter at 50mph. Under normal acceleration the converter now locks up at 55mph. Under heavier acceleration 50% throttle or more the converter tries to lock up at the factory location (50mph) then unlocks quickly then locks where I have commanded in the tune.

Using hp tuning on an early 04 with TTVA cable. Not sure why under light acceleration the converter lockup would follow the tune table and heavier acceleration the converter doesnt know what to do.
