The MAX Stage 3 X47 Box will deliver all the maps required to tune any X47 or X47R turbocharger. Dino results since December 2016 have proven power levels well over 330, and in some cases with the very best hardware and fuels over 350 bhp. It can also deliver Maps for many other turbos such as the S242, S270, RT330, VT330 and has proven power levels approaching that of the X47R.

MAX originally developed crackle mapping for VAN applications and has proved very popular over the last 5 years with Golf GTI and S3 owners. MAX has engineered these "crackle" maps very differently from previous ones you may have seen running on Renault Clio's and Megan 225's. Instead of adding extra fuel in like the rudimentary Renault maps, the MAX ST180 crackle map uses very specific ignition settings and uses the fuel already in the combustion chamber. Furthermore, to prevent the map from popping and banging non-stop, it has been engineered to make the crackling sound between a specific midrange rpm.

This enables you to drive through town normally without attracting unwanted attention and giving you control of when the car crackles.

As for the sound, in our eyes it's just right, adding to the excitement and enjoyment of the car. Giving you that WRC feel when you are out on a B road blast.
