With the Revo 40% Black Friday deal, it more or less offsets the cost of the SPS, so could look it at as getting the SPS for free in effect.
The waffle on the Revo site says that setting 1 is stock mode, but I assume from your post that this isn't truly the stock map back in the car. Whereas with Racingline I would be actually changing the map myself each time? However, I don't I don't have a Windows laptop or a 20 amp battery charger, which rules that out unless I want to spend more cash.
There is also the Mountune Smartflash as another DIY option. Slightly cheaper than the above 2, also offers a supposedly clutch friendly low torque map. I used to own a Focus ST and Mountune are highly regarded in those circles, but whether they are good in the VAG-world I do not know. I don't know if this functions more like the Revo SPS or the RL PDM though.
