Here is the sample Jyphon code for MSLP,  I am going to add this to the system 
library.

def wrf_mslp(PSFC, HGT, T2):
  temp = noUnit(T2) + 6.5 * noUnit(HGT)/1000.
  pUnit = GridUtil.getParamType(PSFC).getRealComponents()[0].getDefaultUnit()
  ee = 9.81/(287.0*temp)* noUnit(HGT)
  exp1 = GridMath.applyFunctionOverGridsExt(ee,"exp")
  msl = noUnit(PSFC)*exp1*0.01 + (6.7 *  noUnit(HGT)  / 1000)
  mslp = newUnit(msl, "MSLP", "hPa")
  return mslp
