Definitely huge potential there, especially if the owner is willing to do a larger turbo and plumbing like the guy in your example did.
The stock turbo is small and meant to spool up and run out of steam very early in the rpm to maximize low end torque. The turbo he installed moved peak power to the high rpm range. I'm betting he introduced some turbo lag as well, but it pulls like a friggin banshee on the top end.
Even with only a tune, you can expect decent HP gains, but huge TQ gains. But thats just in the low end of the rpms
