Jdm tune

What all does the Jdm tune on a 2013 roush supercharged engine change?

I just got the tune on my truck and was just curious if anyone knows.

What Tune was on there before?
How long have you driven on that Tune?

If you're changing from the Roush Tune it's mostly about the Transmission shifting and shift points that is vastly improved.

For power, not much would be noticeable if you didn't do any upgrades.

What Roush setup do you have?
There are many different setups, from 500hp to 700hp at the crank.
From Stage I to Stage II, bigger Throttle Bodies, smaller Supercharger pulleys.
