Default apr stg3+ vs stg1 graph overlay

<center><img src="http://pictureposter.audiworld.com/9579/apr_stg1_vs_stg3.jpg"></center><p>anyone do this yet? It shows how the 3+ loses a little low-end power, and a lot of low-end torque. But gains are tremendous at the higher RPMs

I can do another one against the stage 3 if someone is interested.

interestingly it seems the graphs don't quite line up. Perhaps one is off a 170HP car and the other off a 150.

Default i coulda told you that, obviously the k03 will spool quicker and give better low end than 28r

but once that 28r spools, then its super easy to keep it in boost all the way up through your gears... therefor bye bye chipped a4

Default Similar chart but with all stages....

<center><img src="http://pictureposter.audiworld.com/264/apr_stages.jpg"></center><p>I think the most compelling thing is the low-end difference between 3 and 3+. Stage 3 crushes 3+ by 100 ft/lb of torque at 2800 RPM. It would almost have to be a better daily driver than the 3+.
