Does anyone have any experience with REVO. A gain of 10-20hp is claimed. Sounds interesting...

I got it on my RS4 but I have not dyno tested anything. It feels like there is more power down low and the entire curve is much smoother now during acceleration. So, the claimed 10-20 hp is possible I am pretty sure. It is very difficult to feel few extra hp at the top end without dyno, but it doesnt mean it is not there. Either way, I am happy with my Revo and do not regret spending money on it at all.

Tuners don't do dyno runs without a baseline...
