2018 Infiniti Q50 3.0T tuning -- anyone planning on the new VRX70 turbos?

Hello,

I recently purchased a Q50 with tune and exhaust. I was happy to just leave as is for a daily driver but now with the launch of these new Z1 turbos i really want to explore tuning again. My car currently has an ecutek tune loaded by jtune on it, locked -- can i flash over that with my HP tuner back to stock and then start working on my own maps? Once i feel comfortable with this platform im going to order those turbos and shoot for a 17psi on 93 octane map.

I havent purchased the credits yet for my Q50 but i am ready to.
