1999 Lexus GS400 Precision Dragoon stall converter

[GS400Dex]

I've been doing research on my old GS400. The dragon converter claims big increase at rear wheels over stock. 40 h.p
Is this true ? If so can anyone tell me there experience before and after installing the stall converter & transmission cooler. Thank you..

no horsepower increase but .4 sec reduction 0-60 should be feasible
