What were the weight savings from removing FW 190 outer wing cannons?

Hi:

I have read that sometimes, some FW190 pilots had the outer wing cannons of their planes removed to save weight---especially with earlier marks of FW(A2 thru A5), where the outer cannon was the older MG/FF with a very different ballistic performance that the MG150/20 of later FW marks; So...how much weight did this actually save & how much of an improvement did it make in the performance of the FW? I imagine the reduction in firepower was moot, given that MG151s were much harder hitting & had a higher velocity & rate of fire;

Thanks, ahead of time;
