I don't think a simple remap will do it, for one thing you generally need to fit a higher throughput induction and exhaust systemto handle the extra gas from the turbo.Be aware that doing this would invalidate your warranty and also your insurance unless you declare it.
Try Superchips Bluefin. Plugs into OBD II socket in storage space below steering wheel, downloads ecu data which you then send to superchips via a computer (takes about 20 mins to read data). Superchips will then send you a new remap which you upload to the bluefin unit, plug the Bluefin back into the car and it uploads the data to the ECU (again takes approx 20 mins) extra 32 bhp and 84 nm torque.
I have had my Bmax remapped. I had it done by Phil of EcoPower Remaps of Doncaster and after much research by me and talkingit over with Phil, he gave my car a Quantom remap and took it upto 120bhp (a 26% increase) and upto 270nm (a 26 % increase). All of which I am very, very happy with.
Engine damage? I'm not sure what he can do about engine damage resulting from an engine remap? If I decide to kick its head in, I surely can't expect to claim against the garage can I? He does do some in depth checks on the electrical componentslike the ecu and he asks about the oil and cam belt changes. a
