To get more HP, one would typically be looking for a turbo that would have its higher efficiency at the air flows of 5500 RPMs. So a larger turbo can often satisfy that objective, but simply adding a larger turbo can upset the balance and responsiveness. So HP is not the only objective. On the other hand, a HOT ECU can easily find the that a stock turbo, and IC, can be undersized for the higher pressures or mass air flows. Getting off the line, the larger turbo can be slower to get in boost than the one that is 'undersized'.
I am not trying to say that this larger turbo is not a better all around improvent; just pointing out that a dyno HP result is not the total objective. Finding a balance of resposiveness and peak power is the objective. And that balance will be different for a track car VS a daily driver.
So more about how it feels on the street?
Running stock Viggen IC?
