fyi, the r34 smic is an upgrade for us r33 folk. im running 10psi (rb20 actuator controlled) on full 3" zorst, metal cat, r34 smic, pod (wank) and standard ecu. 11psi is "safe" in my opinion. my car has been in this state of tune for atleast the last year, and i have a heavy foot. no issues
remember, the dyno is not 100% accurate to road conditions. the airflow especially mainly caters for those with FMIC (big fan pointed at the front bar) but doesnt look like it gets much air to the side mounts. keep the EBC. if you plan on modding further it will come in handy
