I was wondering if anybody has installed one of these? It is supposed to make the car go into overdrive at WOT. The only thing that we may need it for is for drag racing (and it would come at the very last second of the race if we did). SO I was wondering if for those who might have installed it if it would be worth it or not. I am still not sure if we will need it because our RPMs read less than 4000 at WOT in third, around 80 mph. I just don't know if when we will get around 90 mph or so and if we will need to shift into OD. Any help would be greatly appreciated.
