Does anybody knows if I need to changed the Load rows and RPM column when I upgrade to Apexi map sensor.

What other parameters do I need to changed.

Thanks

Just change the sensor to "Option 1" , don't change the Map references unless you are planning on tuning the car to much higher boost.

I am planning to go higher boost. I am already in the bottom of the map.

Then yes you will need to adjust the map reference tables along with all the corresponding timing, fuel, and correction values for all the rows and columns effected. Hopefully you also have some sort of auxillary injection or you are running race fuel to allow the higher boost. The map sensor can read 2 bar of pressure but that does not mean you can just crank up the boost without the proper supporting mods and LOTS of tuning. You may already know all this but just offereing up a friendly FYI
