I bought James's old stock BOV for my GTST yesterday since he no longer requires it. I have never had a re-circ tyoe bov on the GTST in the 2.75 yrs of ownership, How much better does it run. Nice crisp return to idle when you come of throttle, no snap, crackle, pop between gears not to mention sounding completely different to drive. Might have to get my finger out to fit the stocker onto the GTR, much bigger job though. THANKS JAMES, if you ever log on today.
