Re: Explaining HFS kit to tuner
The diesel market is growing but power is limited by RPM. Upping the boost and fuel merely produces more and more torque within the same power band. It is nice but gear boxes are not designed to take that kind of stresses. It is kinder to the gear box if power is increased with added RPM.
There is limited crank-angle/ diesel'ing point shift to push the power band upwards.
