Welcome bud.
You need to make sure that you have the correct map loaded on your PC to realise the best results from your setup. Also is a good idea to compliment what you already have with some DNA stage 1 and 2 air filters. ( Contact Captain Moto for a forum price)
As far as greenlaning goes, people have had pretty decent results on and offroad with Avon Distanzias on the std 17" wheels. they have a pretty aggressive tread block but are not murder on tarmac. Check them out mate.
