the vast majority of owners take a trip to warrington to Tuning Developments - regardless of where they are in the UK! You will need a piggyback ecu as mentioned above - the emanage ecus have always been popular (EMB on offer at moment for £550 supplied fitted and mapped at TD). To get the most out of a remap as stated above you need some modifications - ie front mount intercooler, boost controller, exhaust, decat, manifold- if running a ct9 (standard turbo) then these with remap should get your around 185-195 depending on the health of your engine.
