Dealer Performance Upgrade Kit

Has anyone any experience/knowledge of performance upgrade kits supplied by BMW dealers? Advertised from about £900 plus fitting for approx 10% increase in power/torque which if true may be a good compromise rather than P/Ex up to 525/530D with all the hassle involved.
Particularly keen to find out if performance/economy is noticeably different and impact on insurance quotes(if disclosed!)
