Being fairly new to the forum this may have been asked before,couldn't find much on search.I am thinking of have my vehicle "chipped"and have read lots of the commercial literature extolling the virtues, reduced fuel consumption,more bhp and extra tourque.But would be grateful for any feedback from fellow MH owners who have had the this done,ie,does it work are there any drawbacks or potential problems?the most common method seems to be "remapping"but because of the age of my MH (1997 mercedes sprinter)It seems the only option iin my case is to replace the "chip"this apparently has the same effect and costs about the same as a remap.Any thoughts gratefully appreciated.
