Having tested many different power tuning products including ecu remapping we decided to offer the PSI boxes and Autologic ECU remapping.

Both systems offer good power improvements without going "mad".

Ecu remapping offers the benafit of being untracable but should the Engine ecu need to be remapped to repair a design fault within the orginal map you will loose the power remap and need to return the vehicle to us with prove of purchase to have the power mapping re-installed.

PSI tune boxes are a plug in unit and so visable but removable, so transferable to another vehicle or resellable should you decide to change vehicle.

Many of the PSi boxes have power adjustsable settings, however the increase on the base setting is normally all most customers need to make them smile. The higher settings are available but more engine improvements would be required to use the extra fuel being delivered to thje engine (larger intercooler) and on some engines (TD5) increasing the power to this level may cause other problems like cracking exhaust manifolds.

Example of power increase

Discovery TD5 35 extra BHP @ 3700 rpm
