How do you up the boost on MK1 VRS? Also do I need to do anything to do it? Thanks.

To up the boost you'll need a remap of the engine ECU.

Remap!

Hi I suggest a stage 1 map from a reputable mapper. As long as your Octy is in tip top mechanical condition then it will transform the car.

As sugested just get a stage 1 map from decent tuner. Most go with shark, r tech or revo. As said car needs to be running spot on, if not a remap will soon find any weakness with your car and make any problems worse. Most decent tuners will do a health check first and will refuse to map it if theres any probs. Seems harsh but its the best way

There are other ways of upping the boost but just in case you missed the main theme, REMAP!
