MAXD - ST250 Custom Tuning Perfection.
Many rolling road hours and days have gone into developing the MAXD-OUT Focus ST250 EcoBoost software.
Testing has shown the Stage 2 recalibration to be one of the safest and powerful custom tuning solutions available.
All Factory Safety features such as Knock Control, Barometric Presure, and Air Temp correction are all still in even in the harshest of climates and poor quality fuels the engine will be kept safe by the ECU programming.

The MAXD tuning device allows you total control of the vehicles engine calibration.
This Stage 2 version of the device contains the first  3 engine calibrations to choose from not just one like other tuning boxes.

 Stage 1,   Stage 1+,   Stage 2..

Alternate tuning files and custom dyno tuning is available at the head office facility on request.

Software recalibration doesn't come any better than this, ask your software provider for similar graphs.


COBB Access Port vs MAXD Stage 2 Mapping

The Graph shows results from MAXD South Africa Dealer Stealth Tuned in Durban
The graph shows power in KW at the wheels as being 199KW which converts to 267-268bhp. When converting the wheel bhp figure a common rule is to calculate transmission losses in the region of 12-15%. When adding this to the graph the 199 wheel KW is converted to 300-305 bhp. Sorry we forgot to mention the most important fact, Torque was a huge 474nm, 55 more nm than the COBB Accessport.

So what are you waiting for ?  the new name out there is MAXD
24kw (30bhp) and 55nm more than COBB Accessport
