Check all the air piping it usually splits resulting in no performance from charger, if thats OK then the bypass valve into the airbox is the next favourite.

even in Standard form these cars go really well with lots of low end torque.

For details of how to upgrade power search my threads done loads to mine and now running just over 270 bhp
