That dyno is for the stage 3 setup. He technically doesn’t have the stage 3+, because it doesn’t exist for his car but with the APR front mount which is an upgrade from the stage 3, it will produce some more hp.
The reason why it took 490 days, by the way, is that he was waiting on the stage 3+ which has been in development since he won it and is still not out. When he won it, APR never imagined an Audi guy would win it at a VW dominated car show.
Apparently, APR is more concerned about getting a kit right and reliable, then just getting it on the market…
