If gauges are available to order, they are IN STOCK, website inventory is UP TO DATE! EURO-spec units are identical to USA-spec, though some functions and calculations downloaded in Race Studio may be unavailable, primarily those used in oval/dirt racing. Note: Euro gauges are sourced globally due to AIM/Mychron USA's supply constraints. In rare cases of defects requiring warranty repair, AIM USA may charge a $50 fee to "convert" to USA spec, in which Fastech will reimburse to the original purchaser.
