Hey Prime, is this graph before the cams and head upgrade?View attachment 38835
zfr6758, 93octane,~28ish peak psi, 100+ temps with a fairly conservative boost ramp and timing. I'm really happy with this turbo and personally don't need anything more. If I were to add to it, it would be a meth setup and push the limits with this still on 93. I could envision 430-450whp for much of the powerband.
