I think if I had better intercooling and the car was catless I could have made 370+whp on 91 octane. My car has actually never been a particularly strong one and mod for mod was usually 5-10whp down compared to other similar cars I've tuned. So long story short, I think this turbo should be easily capable of hitting 380-400whp on 93 octane if all the moons align right.

As for the comparisons to the GT series turbos, the biggest difference is in the turbine wheels. The Garrett GTX compressor wheels are very nice but are still paired with some relatively old tech turbines. They work nicely as well but the newest EFR stuff really does seem at the very least a significant evolution of turbo technology.
