AUII XR8 200kw - Torque Increase

[OzriderXR8]

Hi All

I'm sure it's in here somewhere......

What would be a recommendation on increasing torque on the XR8, I'm not fussed about top end or anything else I can't actually use.

Car is not a daily driver but I still want to be able to drive to Adelaide or similar without ruining the national economy.

So far as far as I know everything is pretty stock with an auto, all it has is a Redback cold air intake and a Redback 2.5" Cat Back single exhaust.

I'm not looking at engine surgery, just economic bolt on type stuff.

Any ideas?
