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 movement under hard accelaration and reduce the occurance of "wheel hop".

Can we mail order the kit?
Yes, the new Pumaspeed ST250 275bhp 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.

Whats a MAXD Box?
A MAXD box is a 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.
