Almost installed, wow forgot how much work that it is to install twins into a truck that never been twined before. Everything is working pretty good. Should be done tomorrow. Had a late start today.

I didn't take a picture of the other turbo, the ATS manifold and the down pipe. Its looking sweet. Can't wait to get this one done to see how well the truck works. Tomorrow we should have the injectors in, and the twins on. At that point we will do some boost leak checks and some basic wastegate tuning.
The GT3788R is one sweet looking turbo. The stocker is dwarfed by that S475.

Brett did an awesome job on tig the pipes together. I hardly had to grind anything. Can't wait to see how it works. You might need to upgrade your boost gauge, as you only have a 60psi gauge. This set-up should easily push hard till 80psi and the drive pressure should be 1:1 ratio to the boost.
