BrayG60 0 Posted March 29, 2010 Hi i was just wondering is it worth fitting a blow off valve to my G60? would it make that much of a proformance change? they say it can give u 200% more low down power, and will make the whole charger system run cooler. Any help let me know Thanks. Quote Share this post Link to post Share on other sites
