I was bored with the 4 barrel n/a setup, it was a power improvement, but hauling stuff uphill with my heavy truck, I found it would be nice to have more power, especially under load.
I pulled a car trailer with some stuff from my apartment on it and a bed full of stuff last week. going uphill, I just gave a little more throttle, and it almost instantly goes from vacuum to boost and shortly builds up pressure. I lugs uphill with ease under load now, and accelerates better than ever! I do not even have the setup dialed in yet.
It is a 4 speed manual trans by the way. Running 91 octane currently.
