Webiste Mobile speed issue

Hello, I am having following issue

My clients website had pretty low website speed (both on mobile and desktop) but I was able to get it to good (1.5sec for desktop and 3.7 for mobile) and in order to improve mobile a little more I deleted GA tag from website since he was not even using it. Now the speed got back to 6 sec for mobile
