2015 Roush

[kbanford]

Hey guys, I'm looking to squeeze a bit more power out of my 2015 Roush mustang. I'm considering getting the Roush Phase 2 upgrade but I'm also considering leaving it factory boost and just getting a new tune. Does anyone have any experience with this setup?

I went a different route. I asked my tuner how to get 700whp upgrading the Phase 1 kit that was installed on my Gen 2 car when I bought it. He recommended Free Flowing Exhaust, VMP Twin Jet 69MM Throttle Body, JLT 125MM Intake, NGK 6510 Spark Plugs, 79MM Supercharger Pulley, 90MM Idler Pulley. That got me to 705whp at a mile high of elevation on 91 pump gas and 10psi. I wish I would've seen how much power it made stock with the Phase 1 kit, but I can tell you the car is now a completely different animal. A little pricey but overall worth it with how different the car is now.

Impressive. I'll be running 91 octane as well. That throttle body seems to make some good gains. I allready have corsa extreme exhaust but have stock headers/cats.

That's what I've been running for several years. I love it. Zero issues.

This is exactly what I did to a T.... I made 723 to the wheels on MS103. The only thing I bought that I had not installed and have for sale is a Carbon Fiber JLT intake pipe which is supposed to pair extremely well with the the VMP Twin Jet throttle body. I went TT so I no longer have any use for it.

Are either of these two packages good? Seem kinda expensive.

I don't see what the difference in packages is. Looks like the same pulley, injectors, etc.

Second one includes the twin 67 throttle body

Aww.. Guess I missed that. I can't say I noticed a big difference at all with the Throttle body added to my previous setup, but if it's all going in at once and you can afford it, I would do the stage two. If money is tight, do stage 1, and the throttle body can easily be added later.

20-ish HP on that kind of setup. Not a huge gain.
