Well over the course of this winter I am doing a drivetrain beef up. I just got my 12 bolt moser installed. So next step is the tranny. I am going to order one of the beef up kits on this website www.700r4l60e.com I am going to get the 4l60e street/strip upgrade.
First do I need the vacuum modulator, and what other things do i need to order for this upgrade.

I am currently running a TCI Streetfighter 3500 stall. I am going to change to a fuddle hp/street converter with 4000 stall as recommended by them for my mods. Figured while I have the tranny out for upgrade might as well change the converter. So my other question is will I need to have the car redyno-tuned or will it run fine. Any help greatly appreciated.
