Sounds like my old line- Just because something is legal doesn't mean it's a good idea....

I installed this cam last month on my ls1 2000 FRC corvette and it made 363whp/365wtq. When I had it tuned, mods were stock air intake, ls6 intake manifold, long tube headers with stock cats and stock titanium z06 exhaust. The tuner told me my stock air intake was a bottle neck and the stock converters were getting too hot. Car has 27k miles. So I now have a Corsa extreme exhaust system and high flow 200 cell count cats that are going in.
I also installed a Haltech intake mated with my stock open airbox and a k&n filter. This was dynoed on a Dynapack. My tuner told me his dyno does read low. I also ran out of injector the first time he tried tuning it. Stockers were hitting 117% duty cycle. My year came stock with 26lb injectors and now have 42lb Bosch injectors. The numbers stated above is the tune completed with the newer injectors. I haven't had the car retuned or dynoed since the exhaust mods and air intake mod.

Just swapped mine in last night after work. First ever, in car, LS cam swap for me. Took 3.5 hours from start to finish using the Home Depot wooden dowel method, lol. Fired right up and sounded good. I put it in my previously turbo'd 6.0. 4L80 with tight 3000 stall. I run Open Loop Mass Air ONLY tune. My car seems to run better this way, as compared to a Speed Density open loop tune. Or any closed loop tune. Might be different now, but I wont know for several weeks.
Forgive the sideways video...

My car has a 6.0, originally built for a turbo setup, with a "tight" 3000 rpm triple disc lockup converter.
Also has 3.73 gears in a new Trick Chassis 9" rear that started life as an axle & housing package, to which I added the center section, with "N" case, Daytona pinion support, and a Detroit Locker.
Have broken TWO stock aluminum driveshafts so far...Number 3, I swapped in yesterday, after a failure on Saturday while datalogging the new setup...
I have a new Strange driveshaft ordered, but the Holidays have slowed that up, evidently.
Anyway, did some very minor idle tweaking and some small AFR changes.
The new cam seems to want LESS fuel at IDLE and CRUISE, but wants MORE at WOT...compared to old Bullet Turbo cam...
Car idles great at a mere 800 RPM, whether it is in Park, or in Gear.
No surging, no bucking, no eye burning idle...VERY pleased with how easy it was to dial in.
The old turbo cam had some odd turbo specs (adv 280/276, 576/576 lift, unknown LSA), but this one idles much smoother (meaning engine rock steady, but more lope) and way more consistent than that one did.
Literally drives like a stocker in this 6.0.
Old cam was DONE at 5600 or so...once turbo was gone
This one, so far, I have tuned to shift at 6300, and it seems to want that raised a bit.
Used to bark the tires nicely on a WOT 1-2 shift...now spins 20 feet or so, on a WOT 1-2 shift.
I like the mild, but noticeable cam lope. I HATE the ones that sound like they are running on 2 cylinders, like a WRX Subaru.
Warm Idle, Cutout open:

"Street" tuning", i'd call it, although I just found a guy fairly close who has his own dyno that you can rent for a tuning session, at a very reasonable cost.
I'm no "tuner" by any stretch of the imagination, but I scored an old, original "serial" version, HPTuners setup about 11 years ago, now upgraded to the MPVI Pro.
Back when I originally got it, the HPTuners forum actually had several people on there, who would go out of their way to help guide you, and point you in the right direction.
The awesome thing about having your own software, but being far away, is that there are at least a few knowledgeable tuners who can get you dialed in pretty well, remotely...via emailed tunes. Several years ago, my buddy had a radical Z06 that had it's tune butchered by an infamous tuner in the Carolinas, then re-butchered up this way by a local tuner...I reached out to Frost, who with 4 or 5 datalogs & tunes emailed back & forth, got the car running better than it ever had.
On this car, which is my first "cammed" car tuned by me ever, Hardtop Brian (who runs a SD tune) was gracious enough to share his tune, so I could get an idea what, exactly, that he had to change, to get his similarly setup car idle-ing and running well. 99.9% of what he did can't be simply copied & pasted (which I had no intention of doing), but it did give me a reference, without having to deal with the HPT forums.
Luckily, I didn't really need a whole lot of tweaking, and even though I have been running OL MAF ONLY, I plan to do some VE (OL Speed Density) tuning and ultimately want to see how it runs with a Short Term Fuel Trim, Closed Loop, MAF/VE tune.
That's how I tuned/run my truck, and it runs very well

03 gen3 4.8
ss2 cam pac 1218 springs
sd80 injectors
eBay gt45 69mm turbo on 10psi
th400 rmvb off foot brake
fti street racer 2800 stall (more like 3000/3100)
3150lbs 99 mustang
10.68 @ 124mph
car put down only 453 on the dyno but that was with a turbo that was eating itself up and sky high iat’s bc of that. Was running too small of a oil feed restricter to the turbo
if you use a hp calculator based off my et and weight it says I’m a little over 500 now

First dragstrip trip of 2019 for me.
The "SS2" cam seems to really like nitrous.
Last year, the best my car ran, with an unknown turbo spec'd cam, was 12.40@112 NA, and 11.21@122 with a 200 shot.
Today, on motor, went 12.20@113 NA, but 10.69@126 on a 150 shot.
Exhaust, intake, throttle body, gearing is all the same as last year, but I now have a Strange chromoly driveshaft, and a Trick Chassis 9" rear with a Detroit Locker. So a good bit more mass to move, and less nitrous went quite a bit faster with just the cam swap
