Hey Ray,
Firstly congratulations on your purchase!
I'm guessing that because you have the R-line it's the 162TSI motor? If so then it's the same as the standard Tiguan 162TSI and Mk7 Golf GTI. Also Mk7 R turbo is a direct bolt-on so there's some good upgrades that are available off-the-shelf.
I'd check out these few threads first and once you finished reading if you have any other questions post them up in the relevant thread:
Tiguan Exhaust
Mk2 Tiguan Tuning
Tiguan IS38 and Big turbo upgrades
