thanks yudelicious. so i can get a manifold costumized with a egr bung and a downpipe with a cat. then i can run a greddy emanage. but can i have the ecu tuned by jwt then fine tune it with an apexi fc

I'm not sure if JWT tunes obd2 ECUs or only obd1, as mentioned before, you'll need the obd2 ECU for emissions. In theory, as long as you have all the emissions equipment (obd2 ecu, egr, cat w/ O2 sensors, all the other auxiliarry wires and goodies) with a good tune you can pass the obd2 test in a state like Ga. You can probably even ditch all that (except the obd2 ecu) and just "fake" the o2 and egr signals with resistors. You might want to check out ka-t.org, I don't really keep up much with ka-t stuff anymore. The greddy is such a compromised kit though, I think most people obd2 people either just forsake emissions completely and find some other way to pass or just use the resistors trick to emulate egr and o2 signals. Find your way to ka-t.org, it has a ton more relevant info.

Also, I find it ironic/symbolic that a NA KA thread has turned into a KAT thread.
