Common responses are “your car will stall,backfire, run rich, go slower, or rip a hole in the space-time continuum that will bring about the end of the universe”. Certainly, if the BOV is not designed or adjusted correctly, at least some of these may be true.\u003c\/p\u003e\r\n\u003cp\u003eWhen you vent a BOV to atmosphere, you’re letting air out of the system that has been measured by the airflow meter, so the ECU will continue to inject fuel for that missing air, hence the issues with over-fuelling that can occur.\u003c\/p\u003e\r\n\u003cp\u003eHowever, by controlling HOW MUCH the valve vents, WHEN it vents, and for HOW LONG, the Respons can be configured to vent a portion of air to atmosphere at a time and of a volume that least affects the fuelling to the point where there are no negative side-effects.\u003c\/p\u003e\r\n\u003cp\u003eSince our competitors do not have a means for adjusting the amount of air that is vented to atmosphere, they are unable to achieve the same success that a Respons does on even the most sensitive engines.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv id=\"fws_619b60815e88b\" class=\"wpb_row vc_row-fluid vc_row inner_row standard_section   \" data-midnight=\"\" data-column-margin=\"default\"\u003e\r\n\u003cdiv class=\"row_col_wrap_12_inner col span_12  left\"\u003e\r\n\u003cdiv class=\"vc_col-sm-12 wpb_column column_container vc_column_container col child_column no-extra-padding instance-5\" data-t-w-inherits=\"default\" data-bg-cover=\"\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-hover-bg=\"\" data-hover-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\"\u003e\r\n\u003cdiv class=\"vc_column-inner\"\u003e\r\n\u003cdiv class=\"wpb_wrapper\"\u003e\r\n\u003cdiv class=\"wpb_text_column wpb_content_element \"\u003e\r\n\u003cdiv class=\"wpb_wrapper\"\u003e\r\n\u003ch3\u003eIf Everything You’ve Heard Tells You A BOV Won’t Work On Your Car, Try A GFB Respons - You Will Be Surprised!\u003c\/h3\u003e\r\n\u003ch3\u003e“How does a GFB Respons improve performance?”\u003c\/h3\u003e\r\n\u003ch4\u003eBoost holding\u003c\/h4\u003e\r\n\u003cp\u003eUnlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost!\u003c\/p\u003e\r\n\u003cp\u003eThe balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces.

Then, when the throttle is then re-opened, peak boost is reached faster than if all pressure is lost (as is the case with the factory valve that remains fully open too long).\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003ch3\u003eFitments:\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Galant VR4 E84A 6A12TT 92-96\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI 3000GT VR-4 6G72 92-99\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Colt Ralliart All 4G15 06-On\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Lancer EVO IX 05-07\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Lancer EVO VI-VIII 99-05\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI GTO Twin Turbo 6G72 89-00\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Lancer EVO I-III 92-96\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Colt Ralliart All 4G15 06-On\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Lancer GSR 1.8 4G93 92-96\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Lancer Ralliart 4B11T 08-On\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eSUBARU Liberty\/Legacy GT MY10-14 (BM, BR)\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Lancer EVO X 07-On\u003c\/li\u003e\r\n\u003cli class=\"vehicles\"\u003eMITSUBISHI Eclipse 2G 4G63t 1995-1999\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Go Fast Bits","offers":[{"title":"Default Title","offer_id":43023584231676,"sku":"GFBT9033","price":298.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1128\/7276\/products\/go-fast-bits-mitsubishi-evo-i-x-33mm-inlet-33mm-outlet-respons-tms-blow-off-valve-368741.jpg?v=1738947332","url":"https:\/\/jdcustomsusa.com\/pt\/products\/go-fast-bits-mitsubishi-evo-i-x-33mm-inlet-33mm-outlet-respons-tms-blow-off-valve","provider":"JD Customs U.S.A","version":"1.0","type":"link"}
