To be honest, after reading here and there, that's what I expected; no real performance upgrade. But, on my car, I'm sure there is a difference.
Again, I don't know if there is a quantifiable torque difference, but the increased throttle response is undeniable on my car, and that might give me the impression of more ft/lbs. I make no claims on horse power; just thrust and tone.
Maybe it's me. In either case...cool.
