Is an intake required to go stage 3? I have one fitted but would like to go back to the OE engine cover purely for the quietness. I have fitted the Autotech HPFP internals and will be having a BCS exhaust fitted next month so have all the bits for stage 3. I know that VWR Racing dont use an intake on stage 3 in order to improve the mid range power rather than peak power. I also know the K04 Gtis run 300bhp with a simple remap and that with the same engine cover.
