Well, since I did not have a stage 1 or 2 tune from APR prior to taking the leap that I did, I cannot compare how the K04 would compare to a simple software upgrade. With that being said, the largest power gains are in first and second gear. From stock to the setup I have COMPLETELY transformed the car when in light to light driving. If I feel like it, I have tons more power and torque available almost instantly. If you look at the dyno chart above, you can see I am at full boost by 3150 RPMs.

Another aspect of the power upgrades would be fuel efficiency. In regards to fuel efficiency, I saw a substantial increase in highway efficiency but a minor decrease in city driving. I relate that to the fact that I tend to open the car up more than I used to.

I hope that helps to answer your question and if you have any more I would be more than happy to answer them!
