Hi, i've an HYDRA ECU fitted and mapped with many extras, giving around 330bhp/330lbf, the engine blowed a few days ago, now i've a sport cat downpipe ready to fit, with gain can be achieved with this part (power/torque), do i need a remap or can i run the car this way (for a few months at least)?
thanks
Daniel
