JUST FITTED A GFB VTA DV ON MY98 STI RA. FAIRLY HAPPY APART FROM WHEN RELEASE GAS OFF BOOST ITS LIKE HITTING A BRICKWALL FOR A SPLIT SECOND! OK WHEN BACK ON GAS. FEELS LIKE I HAVE MORE THROTTLE RESPONSE. AFTER OPENING UP ON LOCAL BYPASS EARLIER THE DREADED CEL CAME ON BUT ODLY ENOUGH DID NOT GO IN LIMP HOME MODE AS I THOUGHT IT WOULD. NEVER HAD CEL ON IN THIS SCUBE. WHEN STOPPED TURNED IGNITION OFF THEN BACK ON AGAIN IT HAD CLEARED. IS THIS ALL OK AS ITS GOT ME FRETTING? ALSO MY FULL TANK OF OPTIMAX HAS DISSAPEARED EVEN QUICKER!!!PS JUST TESTING MY KYB SHOCKERS OUT, THEY ARE MINT.PPS PAT THE MAPPER IS GONNA SET IT ALL UP NEXT W/E
