"Tweaking the shift" Typed it into Google and got the article here http://autospeed.com/A_110682/cms/article.html

That's really about all you can do before you will need a limited slip differential.

I will give it a try. Sounds easy enough. Did you go to my website?

It's a long read, but let me tell you, the difference is tremendous!

if you want a firm shift, shim the accumulators in the valve body assembly
