I'm sure I'll still be lean, so next is the retune. If the retune doesn't correct it, I'll most likely get a high-flow filter and pressure regulator. If that doesn't work to my satisfaction, I'll go back to 20psi.

I really don't see myself dealing with injector scaling and multiple retunes. I'm just not that motivated and I need to get everything finalized this winter. I already need to install the NW mani's along with the NW dual intake and I'm running out of time for making a winter (-DA) run.
