We are running a 6L LS motor with cnc heads and bigish cam (dont have specs in front of me). Its in our race boat and I am having huge trouble tuning the idle, It will not idle below around 1500rpm and below that the vacuum is erratic and high then the motor just stops.....nothing I have done with the tune is making any difference. anyone have any ideas???
Our previous 5.7 was fine and tuned up fine.
