747 Posted August 10, 2015 Share Posted August 10, 2015 I had a Tunit Box fitted to my last van (2.8 jtd 5 Ton MAM). Not the cheapest but they have a good reputation and they are excellent at customer service. Link to comment Share on other sites More sharing options...
lancepar Posted August 12, 2015 Share Posted August 12, 2015 I have an Italian Box on our 2.8jtd. Unlike chipping it can removed easily, One thing to bare in mind thought is that if the performance of an engine is increased for whatever reason something must suffer like the longevity as well as the mpg. :'( B-) Link to comment Share on other sites More sharing options...
Guest mikethe bike Posted August 12, 2015 Share Posted August 12, 2015 The proper way to do it is with a re-map by a very reputable company that has developed the map on a dynamometer. Boxes and chipping only fools the ECU that the engine is running lean, and alters the fueling to offset the deviation from the mapped value. So fuel consumption will suffer.
