A quality product that makes a real noticeable difference. Don’t mess around with revision g and d diverters, they still leak and do not provide the precision throttle response of this unit. Turbo lag now feels non-existent on my remapped edition 30 (300bhp). Both on throttle tip in (building boost) and lift off and re-application (maintaining boost) this unit makes a huge difference. If you want to turn up the boost on your GTI, invest in one of these!
