Phase One is the best generic remap available for your vehicle. It has been designed to work on standard and lightly modified vehicles to give an impressive increase in power and drivability, taking into consideration fuel economy, smoothness and boost levels (if applicable). Diesel Phase One remaps are switchable between a true factory standard program and a choice of up to two modified programs. Petrol Phase One remaps can be adjusted for timing, boost and fuel to name just a few parameters, using our Custom Settings Software.

As with all of Custom-Code's products the Phase One remap is installed via the OBD-II interface making it a true Port remap. Of course, if your car is non OBD-II compliant, a Custom-Code Chip can be installed at no extra cost.

Our comprehensive database of performance software beats anything that the competition can offer, and also at a very competitive price.

This option should be considered by drivers who want a great performance increase, but do not want to significantly modify other areas of their engine.

This is the ultimate generic remap.
