These days, when an OEM designs an engine, there is more too it than changing the fuel delivery rate/pressure and boost pressure.
OEM’s are constantly striving to obtain the lowest emissions possible and this in itself has a bearing on the overall package of parts that make up a particular model. This will cause an OEM ‘s family of engines to have subtle variances and makes remapping a risk unless the complete package is looked at.
On a good day remapping will give more power and only provide an unknown risk to the operator in terms of compromised longevity of the engine life.
On a bad day remapping will cause an engine to s**t itself and the operator need to accept that he knowingly took the risk.
it is for this reason that people that remap cannot be criticised, but I would never buy a vehicle that I knew had been remapped.
