The BMW 335d is a very capable car but with the right adjustments, it can be transformed into a motorway rocket ship. Our PERON STG1 calibration increases fuel pressure and boost whilst adjusting torque limits accordingly. Part of our calibration allows us to adjust the sports display and apply the remap across all driving modes.  We also work with xHP who offer a great ZF8 gearbox calibration that increases torque limit and sharpened gear changes for an enhanced driving experience. 


  • PERON STG1 remap (from 380PS / 780nm) 
  • xHP STG 2 ZF8 gearbox remap
  • PERON Gel Badge
