I've an 06 plate 2.0 tdi sportback 140bhp I've seen numerous 'wonder' gadgets on the internet promising more power, torque, mpg etc etc. My question, is there anything available that will give me any noticeable increase in power and torque for say....less than £150 ?? Im not interested in the resister things that connect to the MAF and fool the fuel system into injecting more fuel as they are a waste of money. I'm just curious as to whether or not anything is available to give 'Alfred' a bit of a power boost. Thanks for any tips and advice.
