Hi , its a lq4 6.0 with ls3 heads, intake , 42 lb ls3 injectors, throttle body, ls1b controller, return style fuel system . I am running a 3bar COS , its a N/A setup . Everything was running good , I was dialing in the VE . Went for a drive , pulled over did a calibration only flash . It barely started , idles really rough for 10 secs and dies. Did a full flash no luck . Fuel pressure is good , everything checks out ok . Don't know where to go from here . I am attaching my file , any help would be appreciated .
