Hello Jeffko,

If the fuel injection is controlled by an engine management computer the fuel map itself may be the culprit. When the Engine Mamnagement Sytem is installed there is a matrix of Fuel/RPM installed that controls how much fuel is fed into the injectors at what RPM. Typically there is a start up matrix for a new engine that is a little rich to prevent the kind of issues you described. If the EMS was installed with a lean RPM map it would always be lean, melt the pistons and destroy the engine no matter how easy you were on it. When it was run on the dyno this may be where the damage started.

Some EMS systems control iginition only, some fuel only and some fuel/ignition combination.

It may be the place to start asking questions of the people involved and determining the root cause of the damage.
