Where to begin, oh, and honestly, thank you for making a decent valid discussion.
So i've reviewed the Torq Tech website, and here's my findings, please correct if i've missed something or unfairly represented it.

Intercooled Supercharger Kit for the '99-04 Mustang GT - Click for more info.
The Entry level kit you speak of is impressive, offering up 143 HP and 132 TQ over stock. On the Torq Tech website it claims 385 RWHP and 403 ft/lb, I am unable to find your example of 406HP and like amounts of torque. And for a very entry level price of $4499.99 for the entire kit. In their video they clearly show it running 9-10 PSI of boost. The car was a stock '99 GT with only a CAI and cat-back. Here's the interesting part, Taken directly from their website:
Easy, low cost upgrades available to allow for significantly higher boost and power levels when the time comes. Requires only: a built engine, larger crank pulley, low cost fuel delivery upgrade option from TTI and new custom tune.
I've highlighted the part in the paragraph I find most striking. So, to run more than 10 PSI and make more power, you must get a built engine minimum. I know that you're well aware that '03/4 cobras have this factory. So To me this says that's the limit with stock production 2v hardware. This negates you referencing any other HP numbers vs. a cam/bolt on LS1 unless you compare a forged LS1 to your required Forged 4.6. Remember, apples to apples.
So, keeping in the realm of your argument, a stock 2V (we'll get to blown 3V numbers later) you get:
An estimated
455 Hp at the fly, assuming a 15% drivetrain loss.

Same style kit for an LS1
Here is a kit currently offered for the LS1 Fbody by Magnuson Products.
The kit is similar, offering all the necessary hardware and uses the same style of blower as the Torq Tech kit.
Here is the install and dyno numbers, their on PG. 3. Please read the article.

Yes, you are correct, the 4.6 Makes more HP/$ Boosted in this instance for what I can find. On the other hand, 455 HP is all the further you can go by following the manufacturer's kit instructions. The LS1 is around 530 HP at a lower boost level. Both test cars had stock exhaust manifolds and cats. More interesting, and as i've stated earlier, look at the torque curve. The ls1's dyno is nearly flat, making 400ft/lb at 2100RPM compared to the 4.6 making 320ft/lb at 2100. Peak power is made at 4K with the LS1 and 5100 RPM with the 4.6. Broad curves, that's what wins races, not peak.
As for me personally attacking you, maybe. I assumed that you had went with the best of the best hardware including blower, my bad.
And as for your comment on my setup making power, you were almost on par. I have a cam only motor. Stock manifolds, stock Y pipe and stock cat back. Only exhaust mods are gutted cats and a removeable cutout lid before the muffler. Other then that, a computer tune and an air lid. Stock Intake, no pullies, no CAI.
380 RWHP - Verified
460 fly HP (estimated 18% loss, as I have an Auto)
The camshaft manufacturer and several individual reports verify that with the much needed longtubes and true dual exhaust I will see around 480 fly hp. That combined with the soon to be installed 4K yank converter, 3.73's and drag radials should propel my 3620lb sled well into the high 11's, using my current MPH figures. I am told my MPH will increase with the stall and gears keeping me in the powerband faster and longer.
Using your supplied Torq Tech information, you do realize that i'm knocking down THEIR dyno proven SUPERCHARGED 4.6 2v numbers with my N/A LS1, right? I should also mention that these numbers aren't corrected to sea level. They were taken at my corrected D/A at the time of the run.
