Chipping alters the engine management system which controls a number of parameters. These include fuelling sequence, boost and auto box change sequence. You can move peak power and torque parameters around to give you better performance or better fuel economy. Its not a black art but WILL AFFECT YOUR INSURANCE POLICY IF CAUGHT.
My eldest son is an insurance assessor and the first thing he checks on a crashed car is the ECU and if its modified you are fucked ...... he keeps telling me this as I have a toy that produces 210 BHP from a 1.9 diesel engine!
