Yep not bad. But heres the same mag with the Whipple install. 6psi not 8 like the PC. Don't know where they got the prices from though lol.

Yes but the OP has made it a very clear point was he doesn't want a race truck! In my OPINION, a front mount is major overkill for what the OP desires. So my statement of who in their right mind that only wants maybe 450rwhp tops would do a front mount turbo, still stands. If he wants to then oh well, his truck, his choice, just my opinion on the matter after all. 
If money is not an option and if I had my choice I'd run a turbo at 450rwhp. At altitude, turbo's make their own atmosphere i.e. turbo diesel's pull the worlds loads up grades with zero power loss.
At 8500 feet last year I was not making 8psi on my truck. If I had a turbo, I would of been making 8psi.

My statement wasn't against turbo setups in general.. 
Theres nothing wrong or bad about running a turbo at 450rwhp. Lol It was about him going through the fabrication and cost required to do a FRONT mount turbo for a guy that wants no more than 450rwhp. That's just the way I see it though, it may be worth it to you or someone else especially if you have future plans for increasing power.

Makes sense. At that boost level you would need at least 47lb injectors, a fuel system, upgraded MAF sensor, true duals, headers, a perfect tune etc etc.
13psi doesn't tell us jack.
I'm willing to bet you were running out of pump or winding the engine too high.
I ran the hell out of my vortech on 12psi with stock exhaust manifolds. Bumping up to another 1psi would not have blown the engine.

What about a 2007 5.4L with a whipple supercharger, 36lb cobra fuel injectors, and a troyer valve body? This is my daily driver. I have no intentions of going over 8 psi. It's got 89k miles on it now. I also have true dual flow master exhaust 2.5".

get rid of those flow masters and notice a 20/30rwhp increase... Or more.
