A couple weeks ago during my phyco search for info and upgrades I found a post in some other supra related forum. It was a guy who drag raced his and that by disconnecting a white plug going to the trans harness that stop the transmission from pulling timing during shifts he said did go thru trannies a Lil faster then before but it gave him like a 1/2 Or sec off his 1/4 mile.just wanna know if anyone knows more about this. Because i would to create a switch do I can disable the shift retard if was to push it and re-engage for normal driving. I'm just brainstorming guys please help me out. And thanks in advance!
