For a 2018-19 GT with automatic 10s trans and twin turbos, which gear ratio is recommended? Trying to decide between buying PP Or non PP and I’m not sure which ratio would be better. 315 standard vs 355 PP? This will be a highway cruise car with zero track use. Do I need the Torsen rear end that comes with PP? All advice will be appreciated!

3.15, the higher ratios don't work as well with the torque of an FI build.

Ask yourself what you plan to do with the car after the turbo install, then go from there. If you plan on top end runs at standing mile events, go for the 3.15's. If you plan on a lot of drag strip runs then get 3.55's, if it's anything else or somewhere in between the two then just find the car you like and don't worry about the gear it has. The only time the ratio will matter is at one of the two extremes I mentioned, especially with 700+ hp.

consider a 500whp NA build. Way cheaper and more reliable for a street car.
