I've had bellowed up pipes for a while now.
A long long time ago I did some dyno testing to see what some upgrades did.
Stock 2001 7.3 put down 200rwhp.
Adding intake, exhaust, and tunes got us to 280rwhp.
Adding the 38r got us to 310, or 30 HP just from the turbo alone.
Now fast forward a few years with fuel system and 530 hybrid injectors I moved up to a GT4294r and guess how much HP I got from just adding the turbo?
You guessed it 30 RWHP.
