2015 Mustang aftermarket engine mods

I've decided to get the 2015 Mustang, but once I got it I've been wondering whether to stay in the naturally aspirated route, or go to the turbocharger, or supercharger route, since I want to be able to get pretty good horsepower and torque numbers, but still use pump gas or something closest to it?

I doubt staying N/A will gain much power, as it's supposed to be pushing out about the same power as the Boss 302. Long tubes, under drive pulleys, and a lightweight driveshaft will likely help a little, but with each body style, N/A mods do less and less in most cases. You should be able to run a turbo or supercharger system on 91 or 93 octane.

So it would be better to turbocharge or supercharge it? Do you know of any system where there are decent power gains, but can run on pump gas?

It would be better to supercharge. Honestly I don't believe any of the aftermarket turbo kits are anywhere near as good as the aftermarket SC kits. I know I am biased but I have built both and a V8 with a mild boost supercharger is as reliable and easy to live with as a stock engine yet will be making 550 at the rear wheels easy.

Which ones would you recommend for use for a daily driver's car?

You should really do a search as this topic's been over a ton. From what I've read the pos displacement systems have the best drivability but don't make as much Hp per psi as turbos. As far as I've heard the only kit that exist now for the 2015 mustang is the Whipple, so your options are limited.

I am running a Roush supercharger on my 2011 5.0 putting down 600RWHP, I run on pump gas (93 octane) with no issues

The upgrades they made to the 2015 5.0 should make supercharging even safer.

I have friends who run Vortech superchargers, they make about the same RWHP, but the boost doesn't come in as quick as my Roush supercharger. So far a daily driver, I feel the Roush, Whipple, Ford Racing are a better choice

If you keep it around 550RWHP no fuel mods are required, other than the larger injectors in the kits. If you want to get 600RWHP or higher, a boosta pump, injector upgrades or both would be good insurance

What do you mean by good insurance?

Why are you asking people to answer a question for you when you've provided absolutely 0 information other than "2015 Mustang"?

The best systems I've seen for the 2011-2014 5.0s are the Roush TVS 2300 systems and the Hellion twin turbo. I'd personally go with the Hellion, and I'm sure they'll offer one by 2017 for the 2015 once it's out. You'll probably be looking at 600-1300 horsepower depending on what boost you've got it set at.

Adding a boosta pump, or better injectors will help keep the engine from going lean under high boost

On mine with 600rwhp I was going a little lean at the drag strip, when I installed the JMS boosta pump put my air fuel ratios in a much safer range
