• The larger the engine, the lower the manufacturing volume (and, dare we say, the lower the volume, the better the engine is put together). High-volume/high-speed manufacture usually means more liberal tolerances, which in turn means more conservative base settings for the engine tune to cope more safely with the varied tolerances.
Manufacturers of larger truck engines also have more idea of what their product will be likely to encounter in terms of geographical differences in fuel quality and operating and maintenance environments.
Consequently, the largest diesel engines are likely to be operating closer to their optimum performance than, say, van engines. In some cases it is possible to get something for nothing (or at least nearly nothing), but at the moment we don't anticipate chip tuning becoming more than a niche operation in the HY sector.
For smaller engines, however, engines operating on regular quality fuel with regular maintenance can achieve useful Increases in power and/or economy (but rarely both at once) with a carefully developed electronic tune-up.
Bear in mind that any alteration will almost certainly be frowned upon by both your warranty and insurers. There are undoubtedly some products on sale throughout Europe which are, shall we say, less developed than others. If you are going to have your chips Interfered with, make sure you're happy with the vendor's provenance. In the world of electronic tuning, more than mast, Its a case of buyer beware.
