I was reading a write in gm high test http://www.gmhightechperformance.com/tech/0309htp_lt-1_powered_chevy_z28_review/ and it was talkinga bout blot ons you could do and down thought they wrote this about lock up
As for the second area of opportunity, eliminating converter lock-up, we feel we're going through the traps at far too low an engine speed--around 4900 rpm. TGOW launches hard and rockets through First and Second gear, but noses over dramatically midway through Third with lock-up, dumping about 300 rpm in the process. Dyno tuning has shown peak power to come at 5600 rpm, well above our current trap speed rpm. This explains the weak trap speed relative to ET and could possibly account for a tenth or more in lost ET. It's nothing $10 and a trip to Radio Shack can't cure, namely an in-line switch to disable the converter lock-up, and a 15-ohm resistor to trick the computer into thinking the solenoid is engaged.
Is this worth doing to improve ET and how do you do this with a resistor?
