Not for just a BoV.

Only if you go from recirculating to Vent to atmosphere and even then some people don't bother

thanks guys,just wanted to be sure.

wot about upper intercooler pipe,straight swap from rubber one to a polished alloy one. tune or ok

That's fine too mate, its only really mods that upset the air/fuel ratio. Most other bits the ecu can cope with.
