I have a stock Torque convertor and have noticed that the car kinda loses its pull at WOT going down the 1/4 mile when it goes into third. I've heard of a mod that will turn over the TC lock up control manually with the flip of a switch so to speak. Would this help my 1/4 mile top end by not having it lock up in third? Is it an easy mod ? I have the other tranny mod that increase line press at mid throttle. I will pull 1/8ths at about 80 mph but only gain another 20mph from there until the end of the 1/4. so my trap speed is usaully around 99-100mph.
