does your car have a bov fitted to it? maybe when you go on boost the bov isnt closing properly and air is escaping in turn giving you lack of power and instead dumping all air to atmosphere. maybe another check for ya.
can anyone suggest what bov to fit to my 2001 bugeye
are the bailey ones any good or am i best going for hks or summit along these lines
help would be great
