On my GTI I ran the box with Sport +2 (I think) but turned it down to be a bit less responsive on the R as I think the factory throttle maps are a bit different between the models and it made the R jerky at very low throttle openings.
Both cars are just used with the car engine setting in Normal
I also ran it with a tuning box on a different GTI for a while and it really brought the tuning box to life at lower RPM's too, although I think the tuning boxes have since been tweaked to be more sensitive. I didn't try it on my own GTI as it didn't get used for long periods of time and I already had battery drain issues which I think were linked to a faulty boot light as I noticed the bulb blew after 12 months which suggests the bulb might have stayed on all the time.
If there was one mod I really would struggle to live without it would be the PedalBox.
