Do you need a boost compensator?
Unless you are re-benching and turning the 10mm pumps fuel up (via the pressure regulator) and pushing the pre-boost AFR below 16:1 in order to achieve the correct Full boost AFR, or you are upgrading to a 12mm pump – You do not need a boost compensator.
How reliable is a 1HD-T?
Is 1HD-T common rail?
So does that make the engine a common-rail diesel? No, it still uses a mechanical pump, but the difference is that the injector timing is electronically controlled.
