We offer TDI chip tuning for all TDI cars from 1996-current. There are many benefits chip tuning has over "tuner boxes" and below are a few:
 
  • Repairs factory flaws, such as the hot-start issue found in ’98-99 MK4 Golf/Jetta and New Beetle TDIs. Many ’98-99 TDIs require extended cranking to start the engine if the coolant is warm. All our tunes fix this issue.
  • Higher idle speed for colder climates or vegetable oil conversions.
  • Dynamic EGR control: EGR-on when cold to shorten engine warm-up time (better fuel economy, in-cabin heat, and reduced cold cylinder wear & tear), EGR-off when warmed up to minimize or virtually eliminate intake soot build-up.
  • EGR delete (off-road use only) (tuner boxes cannot suppress a check-engine light).
  • DPF delete in '09 and newer TDIs (off-road use only) (tuner boxes cannot suppress a check-engine light).
  • MAF sensor delete (tuner boxes cannot suppress a check-engine light).
  • MAP-sensor upgrade. Many turbo upgrades need a MAP sensor upgrade to allow full boost to retain factory overboost protection. Some tuner boxes will circumvent the factory overboost protection, and you need a boost gauge to see the actual boost.
  • 100% VW dealer and VCDS (VAG-COM) compatibility. Tuner boxes skew the OBD2 data; the engine computer sees less accurate injection and boost data because the boxes alter them outside of the ECU..
  • … and much more.
