Here's video proof of the increase in power.

That video
shows nothing about conditions and elevation of the road. Its done to sell a product and nothing more. They are showing you what they want to show you to sell a product. I have done several APR Stage 2 and Stage 3 in Audi's I have owned from RS4, S4, etc..over the last decade. APR tuning vastly varies in its results with the outside temp and elevation. I have seen this on the dyno as well with one great run and follow up runs that fall off significantly when mild heat becomes a factor.
