Hell yeah, it made all the difference in the world. I'm not stuck waiting for my car to take it's dear tim shifitng anymore. A upgraded torque converter on a stock auto will shave off 1/2 to 1 sec. Thats a huge gain-Note to all automatic owners. On the downside, the stock friction pads take more of a beating, shortning the life of the stock tranny. I'll have my new one in before the old one dies anyway. Plus, if I go the boosted route, the new tranny will be good for around 450 hp so I'l be on the safe side since my motors not nealy going put that out. And yes, I can launch with the best of them.
