Hey guys, I want to buy a manual boost controller so i can up my boost on my S14 SR. I just wanted to know if I have to upgrade my air/fuel management or it would be safe to just run it like that? I have FMIC, Full exhaust, intake, and walbro fuel pump. I'm lookin to boost 14-15psi. Thanks.

You can proabbly turn it up to like 13 with no problems on that setup.

yes, get a 300z maf and injectors and a ecu
