PATC converters?

[Black2011]

Anybody running one of these? seems like they have a wealth of experience with the 4l60e's and the product looks good. Considering this as a future upgrade, could really help out the less than torquey 4.8

Yank and Precision Industries are the two norms in the GM world. Both make nice tight driving, high STR convertors in whatever stall speed you want. I have heard of PATC but have no experience with them. Billet is nice, multiple disc lockup is is nice and so are higher number stall torque ratios.
