The MAXD Out Stage 4 X-57 tuning device will deliver all the maps required to tune any X-57, 57R, or 57RS turbocharger.
Testing results since 2018 have proven power levels well over 350bhp, and with the correct spec turbo(RS) and hardware/fueling upgrade, you can see up to 450bhp. 
The X-57 Series of Turbochargers has been designed from the ground up with a no expense spared attitude. They feature the very latest spec motorsport internals and state of the art 7 blade CNC Compressor wheels. The turbo housings and internals have all been designed and cast in the UK.
 
They have been testing on road and track since 2018 and have easily proven themselves durable and with out compromise on power and response.MAXD originally developed crackle mapping for VAG applications and has proved very popular over the last 5 years with Golf GTI and S3 owners. MAXD has engineered these "crackle" maps very differently from previous ones you may have seen running on Renault Clio's and Megane 225's. Instead of adding extra fuel in like the rudimentary Renault maps, the MAXD 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.
