Greddy eManage piggyback comes set at 5 psi. I have a profec e-01 boost controller and I can set mine at whatever levels BUT 350Z stock internals are known to blow up around 7+ psi. After internals it will be about 15 psi and about 600RWHP.NotAnotherHonda said:UPPING it to 7psi? what does the kit come set on? 5?
