Just came across this and thought that it might be pretty good to have. Although I can't justify the price of this over a chip if I could find it maybe $100 cheepier I might go ahead and get it. I figure that the chip increses the line pressure through this solenoid. I just like the idea of being able to remove my chip and still have my firm shift without the hassel of a shift kit.
