I have a 99 LS, (obvious by looking at my name). Anyway, mods are apexi ws catback exhaust, jdm integra type r header, and now the comptech icebox. I'm planning on doing act 12.5 lb flywheel and act clutch also. and the car will get the Venom vcn-2000 kit this winter.I guess my question is how is my obd2 computer going to like all this. should I do a conversion, and if I have to do a conversion, can I wait untill the nitrous or do I need it now.
