    Unhappy Ls3 with BFD cam tuning tips

    so i recently swapped my saturn sky with an ls3, with a 229/246 .600/.600 110 lsa 107 icl, i got it to idle fairly stable, but it doesnt like to be driven, slow on the power and slight stumble at mid-high rpms, any one have any tips or insight? ive attached the Ecu file and a quick log around the block.

    More spark. Yours is particularly low, too. Main spark, idle spark...needs more spark everywhere.

    I recently changed my cam to a higher lift cam in a 6.2 silverado. I am having problems at start up. It take awhile to start while cold. After it is warmed up though it starts just fine "sometimes" very confusing. PM me please.

    Your car is asking for 50% more fuel in some areas. leave the spark alone and work on dialing in your maf curve and ve tables.
