Product Description

VAGtech recommend the following components in our Stage 4

  • REVO Stage 2 Software    250 – 275 bhp    270 – 300 lbft
  • 4 bar Fuel preassure regulator
  • Forge upgraded dump valve
  • Forge TIP pipe
  • Performance air filter
  • Exhaust system from turbo back with hi flow sports cat
  • Forge intercooler

As with Stage 3 but with the addition of forge front mount intercooler allowing up to 285 bhp

Stage2 software for the 1.8T is designed to make the most of additional airflow and cooling modifications. Whilst stage2 can be setup to suit just an uprated exhaust with sports or de-cat you will not see the full benefit of the engine/software without using the full hardware list and running an uprated intake. The stock twin intercoolers are good but a Front Mount Intercooler is still a beneficial upgrade. There are many other hardware modifications that can be done to maximise the potential of the engine such as uprated boost pipes and Turbo inlet pipe. Stage2 typically gives great gains throughout the midrange.
