Just wanted to say thanks to all you guys who helped me decide to go vacuum modulated on my 4l60. I finally got my Rock-On tranny and put a Yank TT3000 in with it. Woohoo, this thing shifts awesome and i dont even have a tune for it yet! I know i dont need much of a tune since its vacuum mod but still i didnt know how much of a difference it would make. Thanks to everyone here who discussed with me the pros and cons(not really any) of the vacuum mod.

Thanks,
Bryan
