Rapid Motorsports Dominator 2X I run a custom from Rapid in my stock 6.0 w/L92's
This is in a 2900lb Mustang,N/A Carb setup.
I am sure Mikey at Rapid could design one for your combo.....
He hit mine dead on!
10.19@136.22 with a soft 1.55 60'

Most people over cam the L92's.With the great flow from the heads you do not need a big Cam to make power and most of the time the bigger cams kill midrange.
We haven't done any 6.0's but our 427's get a 228/236 Cam and make 525-555 rwhp 490-520tq depending on bolt-ons.

A mail order tune probably isn't going to cut it on a build like yours. It may be close, but you may have quite a bit on the table.
What is your exhaust setup? Headers?
At that point it may be worth swapping the intake for something that is proven. (L76), your intake is a variable. I recall your thread when you built it, and it was nice work, but without playing on an engine dyno to optimize plenum size and runner length and a host of other variables, you are just guessing.

I see a couple of things I would try with your combo....

I'm going to get one of the tuner packages this spring but I can't see 100 hp in the tune.

When we are used to straight cams or reverse split cams on turbocharged LS1,2,6 heads he proves that the L92 still likes a conventional split cam even when turbocharged. The NA L92s seem to like more of a split, say 8-10 degrees, but his ported L92s on a turbo motor like the 4 degree split he has. I mean, he has a little over 1000 flywheel horsepower on a 370" motor!!

Here's a couple in an LS3 vette with M6 tranny, full boltons, no cats, and 4.10 gears. Both with XER lobes. Comp XER281 made 459hp/442 torque. Specs are 232/234, .595/.598, 112LSA. Torque peaked at 4700 rpm and hp peaked at 5900rpm. Mean idle and cam surge between 1500 and 1900rpm. I think this is the same cam as Tx Speed's Torquer I. I see why they named it torquer. Pulled it because wife didn't like driving it with the surge. Easier to change cams than wifes!
Changed to a Comp custom grind that speced out at 228/236, .619/.610, 114LSA +2. Also changed to an under drive pulley during the cam swap. New cam with UD pulley made 465/412. Torque peaked at 4700rpm and HP at 6400. Idle not quite as mean and little or no cam surge with a little better MPG thrown in. Not near the torque of the other cam. Pulls hard a little longer though.

I spoke with Mike from Vengeance Racing and he told me these heads like big split on the duration and a bit more lift with a wider LSA. Does anybody want to chime in wether they have a different bumpstick where it has a small split in duration and narrower LSA's and how well they've worked for you.
