Focus ST 250 EcoBoost Power Upgrade PS 305 - Pumaspeed Performance Tuning Package

  • MAXD Stage 2 Focus ST250 Ecoboost Tuning Box
  • R-Sport Hi Flow Down Pipe (Decat)
  • Milltek Sport Cat Back Exhaust (non resonated)
  • R-Sport GEN 2 Intercooler
  • Ram Air Induction Kit

Pumaspeed and MAXD have worked on our own Focus ST250 to bring you a power package that has the ability to get you to the coveted 300-305bhp figure.
With a few choice hardware pieces we can transform your ST250 into a properly fast hot hatch. With peak figures in excess of 300bhp and a collosal amount of torque (468nm), the car will have bags of in gear pace leaving behind GTI's, Cupra's and VXR's. Despite all this power fuel economy remains acceptable and power delivery is smooth and progressive, allowing the ST250 to be sedate and humble on the daily commute or cruising around town. The addition of the Milltek Turbo back exhaust adds to the thrill, injecting some much needed exhaust noise and excitement to the car. From installing this kit you will have a true drivers car, exhilarating to drive, powerful and practical all rolled into one.

In this kit you will recieve

  • Stage 2 MAXD box
  • Ram Air Full cold Air Induction System
  • R-Sport Decat Pipe
  • Milltek Sport Non Resonated Cat Back Exhaust
  • R-Sport Stage 3 Intercooler

Pumaspeed Recommends.....
 When tuning your ST250, we recommend the use of Denso ITV22 Spark Plugs to help prevent pre-detonation. These are available as an option with all our ST250 Tuning Packages.
 Due to the high level of torque, we also recommend the use of the low vibration lower engine mount. The standard part is known for being weak. The low vibration engine mount will help prevent excessive engine movment under hard accelaration and reduce the occurance of "wheel hop".

Can we mail order the kit?
Yes, the new Pumaspeed ST250 power kit can be mail ordered and sent anywhere in the world. If you are having this package shipped please select the MAXD Box option in the Mapping Options drop down menu.

What is a MAXD Box?
A MAXD box is a Programming Device that allows you to tune your car via the OBD port using your own laptop. It's a simple and easy process giving you the ability to switch between maps or return to stock whenever you choose. All MAXD boxes are supplied with software and intstruction on a MAXD branded USB Stick.
