    Default Cold Start

    LS1 5.7 HSV with :? Whipple supercharger.Cold start?Fires up ok but then staggers for say 30 secs until it settles into nice idle.If the throttle slightly opened the idle will be ok and settle out after 30secs.
    Have been around EFI tuning parameters in idle,cold start etc,etc, with no success.What am I missing out on.After first cold start thereafter starts perfect.
    When at operating temp a slight opening of throttle produces a slight uneveness at say 0to4%of throttle opening and then clears.
    Anyone got any ideas fo a guy in UK

    have you messed with the BASE spark tables?
