Ratiotek Valve Body differences and benefits

[Horizon5.0]

I’m looking at getting a Ratiotek valve body for my 10R80 GT. My main question is if it’s actually worth it. They have two different models and i’m wondering if there’s a benefit to the PR over the PRX. And is it a simple thing to install that can be done with simple tools in a few hours, or is it complicated and requiring special tools. I don’t want to buy it and pull apart my valve body to find out i need some special tool. and how much of a difference would the RT-10R80-PRX make on a bolt on mustang making about 465whp.

It's pretty simple, take off trans pan, take off the bolts with arrows 8mm and valve body will come out. Everything easily installs, then throw it back in.
