Ok, How about a 3200 stall, & keep the OEM 323's ?

The tires are BF Goodrich Comp 2. I would hope that with the higher stall and these tires, I wont have any traction issues, at least when its dry roads.

Okay.........will the 3600 TC give me traction every time, on the BF Goodrich Comp 2 tires presently in use ?...........I think I read somewhere on here that someone had a 3600 and no traction when WOT from a stop.

If I have slightest bit of wheel spin with that high of a stall, then what's the point.

We have a current thread about those exact tires and drag radials. See the following thread, especially my post #34 and those after it:

One "whats the point" is that the engine will stay in its power band after each shift, instead of bogging down with low RPMs.

I absolutely agree with Ted.

This aspect, "shift extension" (the rpm to which engine speed will drop after an upshift), is about 50% of the benefit of an optimized stall speed. It's not just about launch. The optimized stall speed will also eliminate or greatly reduce WOT "dead spots" (speeds at which the trans is unable to downshift to a low enough gear to get engine speed up quickly), such as that 30-40mph range for a 3.23 A4 car. With the higher stall, even though it's still downshifting to the same gear, engine speed will instantly jump much, much higher (putting you in the powerband) than with the stock converter.
