    new cam lifter install and tune , engine dies after coming down to idle

    seems tobe a little better when AC is on , but when ac is off car will die and wont come down to stable idle after spirited driving . should I just raise idle RPM ( currently at 700 ) cam is TSP STAGE 3 , car is automatic ls3 C6

    Sorry mate you won't get any help without posting the Tune and a decent log , without seeing them it will only be based on guess work which won't help at all

    The above tune should have the coolant fan duty cycle at 90% or below , however im still getting some intermittent stalling at or around idle . That's what im scratching my head over . LMK if the above tune doesn't load . Thanks in advance .

    Post the tune file.

    Your Base Idle airflow or torque follower may be too low.
