A kid in my town just traded his 370z for the skyline and I read online from a few places that it only runs 13.6-14.0 stock. What do you guys think? I have stage 1 ported eqs, a ported and plated kegger, shorty headers, 1.6 Harland sharps, 218/224 cam, 2800 stall, billet 52mm Holley and a custom tune from PIE
