Propane injection

[Hammerhead]

Is this a conversion from diesel to propane? You do know there is less energy in an equivelant volume of propane, so you would need large tanks (pressure vessel cilynders) and would probably have refueling issues, unless you have a dedicated route and this has already been factored.
As a power adder or attempt to increase fuel economy, I wouldn't touch it.
I do know there are Natural Gas & Propane fuel versions of the ISX, as well as Cat & Detroit, but there are hardware changes required. I used to haul countless CNG Cat 3406 engines, I know for sure they use different pistons and turbos than diesel and were not cross compatible.
