hi guys would appreciate your help with this. I’ve recently had a cat back milltek exhaust fitted (non res) which sounds awesome but I’m now looking to do air intake next, which ones do you guys recommend? Ideally want to spend up to £600. Also I already have a stage one map which I had before exhaust, do I need to map it again once air intake done? Or with both done can I go stage 2? Appreciate your comments on this
