It's not the HP, it's the lower-range torque that's worth the money.
I can switch between stock and the OVT on demand (just need my laptop with me) and if you drove my car with the two you'd choose the OVT flash every time.
The difference is not subtle -- at all -- any more than nozzles were on my ALH Jetta.
I took the latter in for a recall and the guy who did the work came up to me and asked "what the hell did you do to that car?" when he gave the keys back to me.
When I had my "6" window seals done (under recall) the guy who worked on it asked me the same thing.
