The Gemini Planet Imager (GPI) is a facility class instrument for the Gemini Observatory with the primary goal of directly detecting young Jovian planets. After several years of successful operations on sky at Gemini South, GPI is undergoing maintenance and upgrades at the University of Notre Dame and is being moved to Gemini North. We present the current performance results, from in-lab testing, for several of the upgraded components to the Integral Field Spectrograph (IFS) and the Calibration Wavefront Sensor (CAL) for GPI 2.0. These upgrades include changes to the IFS dispersion prisms, changes to the pupil viewing cameras, and changes to the low order wavefront sensor. These improvements are designed to improve the magnitude and contrast range of GPI. The IFS prism upgrades are expected to provide more equal spectral lengths across the Y, J, H, and K bands, while the new pupil and CAL cameras are expected to outperform their predecessors in several key metrics. We describe the alignment of several components, their noise characteristics, and their performance in the GPI environment.
