After 5400 or so the gains are much smaller at around 2-4 whp so peak gains are not massive but overall there is a much larger area under the torque curve.
Isn't most (or all) of that gain due simply to the retune?

I mean, I already have the Steeda 91 tune, which picked up about the same HP and torque gains you cite for the TB and tune. I'm probably now at about 440 hp at the flywheel, with redline above 7,000 (much like the Boss). Are you saying that with the addition of a larger TB and another retune, I can add another 20 hp...over and above what the Steeda tune gave me? Confused.
