CRINGE (Cosmic Ray-fitted Intensities of Galactic Emission) is a model used to calculate the galactic diffuse emission of gamma-rays and high-energy neutrinos. These emissions are the result of Cosmic Ray (CR) interactions, mostly proton and helium, with the interstellar medium. The distribution of these CRs in the Galaxy is calculated by fitting the source and transport parameters to the local proton and helium flux measured by AMS-02, DAMPE, KASCADE and IceTop, along with electron, positron, carbon, and B/C-ratio data from AMS-02. In this talk, we focus on improvements of the CR modeling of CRINGE by including new data from DAMPE and HAWC, as well as modifiying the model parameterization. Additionally, we discuss the uncertainty estimation in the high-energy CR data. We present these improvements and their significance.
