Well, it's definitely safe to say the APR Stage III kit is delivering as advertised. Just over a week ago VWBoost posted a USP Motorsports built Golf R with the APR Stage III GTX2867R showing over 400 wheel horsepower and here is another car backing up those results. Keep in mind both of these cars are dyno'd at the front wheels and this is accomplished simply by pulling the all wheel drive controller which essentially turns the Golf R back into a front wheel drive Golf.

Here is the full rundown of mods:

APR stage 3
APR rods
APR flapper delete
100 octane tune
