Claviger's Domination tune with O2 sensor off would be a good starting point to run as is or with a PC3. It is very similar to what I have found that works well. Changing the L/F switch over point either higher or lower can affect throttle crispness if you prefer other than it is. With the O2 sensor on the ECU will adapt to the a/r table if possible (I find this messes up otherwise good tunes so I would disconnect and plug the hole with an oil pan plug and copper compression washer of the right size from your local auto parts store.)
