Me too as above im afraid, save your money or get a remap.

The anolog tuning box's are very crude in the way that they work. Some claim to contain a specific 'map' for that vehicle. Then there are the digital versions but these are big money, infact about the same cost as a bespoke remap, so why bother?

With the resistor box's Ive heard of all sorts of problems, overboost, black smoke and limp mode being three.

One does wonder if it is just marketing when car manufacturers offer same models with versions of the same diesel engine in different power outputs. The 140bhp version might cost £1500 more than the 120bhp version but is it just a different chip & the actual manufacturing costs are no greater for the more powerful version?
