ko4 on it mate, the bloke said that it could of been put up to more that 240bhp, but the intake temps were too high, so better intercooler would bve the option? but dont want to pay £600 - £700 for the forge 1. iv seen others been done for cheap but im unsure of dimensions. have you got a fmic on yours? your spec is pretty impresive have you had it mapped yet?
