What kind of fuel do you plan to run with 17psi of boost? That's too high, even for 93 octane pump gas.
Your oem maf, ecu, and O2 sensors will ensure your a/f is correct. Your problem with being "safe" is insufficient octane, not a/f.

what would you recommend running for boost? What octane for 17 or 18 psi? I am pretty sure I am running 17 psi or around 18 psi on stock twins, I have the intercooler, exhaust , fuel cut, boost controller and so on, pretty much all the bpu's
