HHO LPM for a 10.5 Liter Diesel engine for a MAN truck i am giving around 3.2 liters but no gain up to now.
Happy New Year to you!
You might find that a MAP/MAF would enhance your gains. You should already be having a much smoother, quieter ride with more power and torque, better acceleration and greener results. Just add a MAP/MAF unit to better control what your on-board fuel computer is telling your injectors! You need less fuel and more HHO through your engine.
