I just a 91 hatch with a dohc obd1 zc with a boost kit. i just did a full OEM rebuild. My set up is a egay 50 trim with dsm 450's and FMU and front mount. my question is how much boost can i run safely with a fresh oem rebuild. my ecu is tuned with a sst chip tuned on chrome on 11lbs, is this safe?? any feedback on boosted zc's would awesome.....thanks
