I think a new program for the new torque converter would be a good idea. A flash is always best as then you don't need a chip. As for the shift kit, I still recommend it. The Jerry mod shift kit is basically free since you use your stock valve body and accumulator pistons. All you need are a few gaskets, some new fluid, and a couple of springs to do it. You could always buy a new valve body as well so then you don't have to drill your stock valve body's seperator plate.
As for what I run in the 1/4, I don't know yet but I'll know soon enough. I've been waiting on my slicks and they should be in the mail.....well, in a UPS truck and on their way to me.
