Roush upgrade to phase two question

[beerformeplz]

Just purchased a 2015 GT that had the roush phase 1 added at the dealership. Car only had 1100 miles on it. The original owner told me the Roush warranty was transferable as that's what the dealership told him. After reading about 20 different threads on here I quickly learned that its not. Long story short, instead of waiting on the warranty to expire I can now go ahead and up the boost. My question is instead of buying the phase 2 kit which seems to be $1150 everywhere, can I just buy the boost a pump, pulley and, plugs? I don't need the roush update tune (read enough horror stories on that also) as I'm having a local shop dyno tune it. My goal is 675to the wheels, is that possible with the stock roush injectors? What size pulley will make it happen?

I'm at 700 to the wheels I added a bap id1000s and 79mm pulley the roush injectors will be maxed out at that point.

Thanks for the info, was hoping to not have to got that route yet. Which bap did you use? VMP pulley?

I went with the jms. Heard good things from vmp too. Can't go wrong with either. Yes 79mm vmp pulley.
You may be able to get around 630 to the wheels with the roush injectors but I'm not sure. I'd talk to beefcake or Lund about it.

Yes. You can do 2 things.

1. Go to the Phase 2 install guide and look up the parts list. Call roush and get pricing on the pulley & bap (and whatever else you want out of the kit). They'll sell it separate to you.

2. Call VMP tuning; they have a lot of parts that are interchangeable between your blower and theirs including pulleys and they sell boost a pumps. They'll also sell you a tune or you can just go with your local guy if you trust em.

You'll most likely get better results with the custom tune over Roush, albeit the safety margin might be different.

As stated above, I'd source the components separately and get the Lund tune if I were in your shoes.
