Diesel Performance Packages

JE Diesel performance tunes deliver power and acceleration gains as you'd expect, but we also concentrate on response & flexibility for more relaxed motoring. The real benefits come at higher speed where, with certain models, the standard car needs most of its available power just to maintain speed, leaving little surplus for acceleration. At higher speeds the surplus power available with JE Diesel tunes can be more than doubled.

JE performance tunes are written and developed in-house by JE Engineering and JE Deutschland using the very latest and best software. They are extensively tested on JE owned vehicles in the UK and Germany.  They are not copies!
