The new generation of ST250 Focus EcoBoost is perfect to tune. The Stock turbo can easily run with 300 bhp and give some serious thrills.

We advise the use of a set of forged pistons at this point as the stock pistons are very weak.

But what if you feel the car is a little underpowered at 300 bhp?
Pumaspeed has the answer, combine a very popular X-Series turbo, the  X-37-350 in this case, and the new Stage 3 MAXD Remap and you can hit the heights of 323 whp or over 350 crank bhp with a stable 500nm plus torque. ( More torque is available on request in Stage 3 PLUS map)

The New Pumaspeed Tuning unit will enable you to download any of our tuning files and upload them as many times as you want with the aid of a simple Windows-based Laptop or PC
The Mapping device – FAQ’s

Can the box be used to turn my vehicle back to the original Stock file at any time?
– Yes, the box allows you to store the original file and then allows you to install your stock mapping any time you need.
What happens to my stock mapping?
–  this will be read and will be saved on the Laptop.
What if my car is already mapped?
Your ECU will be read by the software and this will be treated as the stock mapping for your car.
 Is the Software easy DIY install on and off the car?
– Yes the custom software is very simple to use and runs on any Windows Laptop.
 Can I upgrade the maps to a higher level?
– Yes the benefit of the system is that MAXD can easily send you upgraded files from the above list.
Can MAXD write a custom file to suit my list of mods?
– Yes the in-house calibration specialists at MAXD can tailor a mapping to suit you and your driving style. Whilst MAXD research and development does run through most case scenarios there will always be the requirement for that one-off special.
Can i use the device on more than one vehicle?
– No the MAXD device locks itself to your vehicle’s VIN number and cannot be used on another vehicle.
Can I use Different Fuels?
–  MAXD maps are available for 95 RON 98RON and 102RON high-quality fuel. We will make them freely available but warn that running the wrong fuel to mapping combination can be dangerous
Does the Mapping affect the immobilizer?
– MAXD maps will not affect the vehicle immobilizer in any way.
Can I download a stock map?
– If your car has already been mapped elsewhere and you want to return it to standard, we can provide a standard tune.
DO we think it’s the best?
– The Simple answer is YES, internet forum owner testing has shown the MAXD stage 1 mapping to be higher powered than every other branded mapping, including some very well-known names.

The tuning device is locked to the VIN Code on your car and cannot be used on any other car without a full reset.
