Everything else is stock

Only ITR Cams and ITR Manifold

What calibration should I use on the KPro?

Start with either the ITR calibraiton or the 05 RSX cal. YOu will have to enable the speed sensor and OBD2 on the 05 cal.

do i need to enable the obd2 on the itr cal?

I'm going back to stock, but I don't know if I'll bother going back to stock cams and stock manifold. I might just leave the ITR cams and ITR manifold along with the KPro in the car. Would using the itr cal, as is, work well enough.

could I go back to the stock ecu using the itr cams and itr manifold?

It is completely up to you if you enable or disable OBD2.

You will not have the proper timing, vtc or fuel maps for ITR cams using the stock ecu.

the itr cal has a check mark on "disable ignition retard when the engine is cold" and I noticed the other k20a2 310 have it unchecked. what's the reason and should i uncheck it?

Cold retard - enables/disabled ignition retard when the engine is cold. Some vehicles run significantly better when cold if the ignition retard is disabled.
