What is a good FCP, LCP and TTI for an Ionic app

I have been trying to improve the load time of my ionic app. I have gotten my vendor.js under 600kb and the default page loads in about 320ms and I decided not to preload all the modules at load time. I have compressed my files and pruned my node modules. However, Lighthouse is showing my FCP at 5.3s, my LCP at 8.8s and TTI at 7.3s.

Is this normal or am i missing something?
