  Integral Field Spectroscopy (IFS) is well known for providing detailed
insight of extended sources thanks to the possibility of handling space
resolved spectroscopic information. Simple and straightforward analysis such as
single line fitting yield interesting results, although it might miss a more
complete picture in many cases. Violent star forming regions, such as starburst
galaxies, display very complex emission line profiles due to multiple kinematic
components superposed in the line of sight. We perform a spatially resolved
kinematical study of a single Green Pea (GP) galaxy, SDSSJ083843.63+385350.5,
using a new method for analyzing Integral Field Unit (IFU) observations of
emission line spectra. The method considers the presence of multiple components
in the emission-line profiles and makes use of a statistical indicator to
determine the meaningful number of components to fit the observed profiles. We
are able to identify three distinct kinematic features throughout the field and
discuss their link with a rotating component, a strong outflow and a turbulent
mixing layer. We also derive an updated star formation rate for \ourobj and
discuss the link between the observed signatures of a large scale outflow and
of the Lyman continuum (LyC) leakage detected in GP galaxies.
