I MN all chassis dyno tuners are booked to at least until mid July. On my current 80 LS3/4L60E project I sent my computers out to a shop in St.Paul MN for a mail order tune. They should be back this week.
I've also used Steve Frost at Frost Tunes. He's in VA. That was a stock LS1/4L60E combo and it ran great.
If your LS3 is fairly stock I wouldn't hesitate to do the mail order tune.
