    i have a sports cat 200 cell and a precat down pipe with full cat back system, i phoned courtenay and they said a full ecu remap will cure it, they will clear it forgood and increase my torque and bhp, plus i am at stage 3, i.e turbo back system, fmic, large top hat etc, so they said ill wil be hitting figures of 310bhp with 360lbs torque,

    they also said if i dont want to remap my car i can have a standard ecu set up and clear the code for good which is 65quid..
