Ok, so update for everyone.
I spoke to my local Walkinshaw guys today as I've already adjusted to the power. Crazy but i'm thinking more power may be the go.
Apparently they don't have official kits yet but will within the next month. They are saying they will have a kit without any exhaust upgrade or anything should be around or more than the harrop stage 2 kit so i'm looking at around 530kw and 1000nm of torque. Supposedly these cars are pretty easy to get power out of. If I added an exhaust to the kit I would be looking at in excess of 600kw and 1100nm of toque. All the numbers are at the engine by the way. This way I also keep my factory warranty and there are no harrop people locally so I get someone I can go and see if I ever struck and issue.
Any thoughts from you guys? Am I being stupid as I'm kind of hoping long term this may be a collectors car? Or I could be totally wrong? More power calls me but at the same time i'm a bit unsure if its wise
