Yes that's streetable. As long as you have meth injection & the correct electronics to protect your engine.
I run 20-23 psi on 91 octane on my V-6. It's that high because the heads are that restrictive.
Hmmm, better gas mileage,,,stay out of boost. Run as much total timing as possible when out of boost. Hard to do when you do not have electrical devise to say when & where you want high total timing. MBHD
